+# BGPT Paper Search
+
+## Overview
+
+BGPT is a remote MCP server that searches a curated database of scientific papers built from raw experimental data extracted from full-text studies. Unlike traditional literature databases that return titles and abstracts, BGPT returns structured data from the actual paper content — methods, quantitative results, sample sizes, quality assessments, and 25+ metadata fields per paper.
+
+## When to Use This Skill
+
+Use this skill when:
+- Searching for scientific papers with specific experimental details
+- Conducting systematic or scoping literature reviews
+- Finding quantitative results, sample sizes, or effect sizes across studies
+- Comparing methodologies used in different studies
+- Looking for papers with quality scores or evidence grading
+- Needing structured data from full-text papers (not just abstracts)
+- Building evidence tables for meta-analyses or clinical guidelines
+
+## Setup
+
+BGPT is a remote MCP server — no local installation required.
+
+### Claude Desktop / Claude Code
+
+Add to your MCP configuration:
+
+```json
+{
+  "mcpServers": {
+    "bgpt": {
+      "command": "npx",
+      "args": ["mcp-remote", "https://bgpt.pro/mcp/sse"]
+    }
+  }
+}
+```
+
+### npm (alternative)
+
+```bash
+npx bgpt-mcp
+```
+
+## Usage
+
+Once configured, use the `search_papers` tool provided by the BGPT MCP server:
+
+```
+Search for papers about: "CRISPR gene editing efficiency in human cells"
+```
+
+The server returns structured results including:
+- **Title, authors, journal, year, DOI**
+- **Methods**: Experimental techniques, models, protocols
+- **Results**: Key findings with quantitative data
+- **Sample sizes**: Number of subjects/samples
+- **Quality scores**: Study quality assessments
+- **Conclusions**: Author conclusions and implications
+
+## Pricing
+
+- **Free tier**: 50 searches per network, no API key required
+- **Paid**: $0.01 per result with an API key from [bgpt.pro/mcp](https://bgpt.pro/mcp)
+
+## Complementary Skills
+
+Pairs well with:
+- `literature-review` — Use BGPT to gather structured data, then synthesize with literature-review workflows
+- `pubmed-database` — Use PubMed for broad searches, BGPT for deep experimental data
+- `biorxiv-database` — Combine preprint discovery with full-text data extraction
+- `citation-management` — Manage citations from BGPT search results

+# Pyzotero
+
+Pyzotero is a Python wrapper for the [Zotero API v3](https://www.zotero.org/support/dev/web_api/v3/start). Use it to programmatically manage Zotero libraries: read items and collections, create and update references, upload attachments, manage tags, and export citations.
+
+## Authentication Setup
+
+**Required credentials** — get from https://www.zotero.org/settings/keys:
+- **User ID**: shown as "Your userID for use in API calls"
+- **API Key**: create at https://www.zotero.org/settings/keys/new
+- **Library ID**: for group libraries, the integer after `/groups/` in the group URL
+
+Store credentials in environment variables or a `.env` file:
+```
+ZOTERO_LIBRARY_ID=your_user_id
+ZOTERO_API_KEY=your_api_key
+ZOTERO_LIBRARY_TYPE=user  # or "group"
+```
+
+See [references/authentication.md](references/authentication.md) for full setup details.
+
+## Installation
+
+```bash
+uv add pyzotero
+# or with CLI support:
+uv add "pyzotero[cli]"
+```
+
+## Quick Start
+
+```python
+from pyzotero import Zotero
+
+zot = Zotero(library_id='123456', library_type='user', api_key='ABC1234XYZ')
+
+# Retrieve top-level items (returns 100 by default)
+items = zot.top(limit=10)
+for item in items:
+    print(item['data']['title'], item['data']['itemType'])
+
+# Search by keyword
+results = zot.items(q='machine learning', limit=20)
+
+# Retrieve all items (use everything() for complete results)
+all_items = zot.everything(zot.items())
+```
+
+## Core Concepts
+
+- A `Zotero` instance is bound to a single library (user or group). All methods operate on that library.
+- Item data lives in `item['data']`. Access fields like `item['data']['title']`, `item['data']['creators']`.
+- Pyzotero returns 100 items by default (API default is 25). Use `zot.everything(zot.items())` to get all items.
+- Write methods return `True` on success or raise a `ZoteroError`.

+## Common Patterns
+
+### Fetch and modify an item
+```python
+item = zot.item('ITEMKEY')
+item['data']['title'] = 'New Title'
+zot.update_item(item)
+```
+
+### Create an item from a template
+```python
+template = zot.item_template('journalArticle')
+template['title'] = 'My Paper'
+template['creators'][0] = {'creatorType': 'author', 'firstName': 'Jane', 'lastName': 'Doe'}
+zot.create_items([template])
+```
+
+### Export as BibTeX
+```python
+zot.add_parameters(format='bibtex')
+bibtex = zot.top(limit=50)
+# bibtex is a bibtexparser BibDatabase object
+print(bibtex.entries)
+```
+
+### Local mode (read-only, no API key needed)
+```python
+zot = Zotero(library_id='123456', library_type='user', local=True)
+items = zot.items()
+```

+# Authentication & Setup
+
+## Credentials
+
+Obtain from https://www.zotero.org/settings/keys:
+
+| Credential | Where to Find |
+|-----------|---------------|
+| **User ID** | "Your userID for use in API calls" section |
+| **API Key** | Create new key at /settings/keys/new |
+| **Group Library ID** | Integer after `/groups/` in group URL (e.g. `https://www.zotero.org/groups/169947`) |
+
+## Environment Variables
+
+Store in `.env` or export in shell:
+```
+ZOTERO_LIBRARY_ID=436
+ZOTERO_API_KEY=ABC1234XYZ
+ZOTERO_LIBRARY_TYPE=user
+```
+
+Load in Python:
+```python
+import os
+from dotenv import load_dotenv
+from pyzotero import Zotero
+
+load_dotenv()
+
+zot = Zotero(
+    library_id=os.environ['ZOTERO_LIBRARY_ID'],
+    library_type=os.environ['ZOTERO_LIBRARY_TYPE'],
+    api_key=os.environ['ZOTERO_API_KEY']
+)
+```
+
+## Library Types
+
+```python
+# Personal library
+zot = Zotero('436', 'user', 'ABC1234XYZ')
+
+# Group library
+zot = Zotero('169947', 'group', 'ABC1234XYZ')
+```
+
+**Important**: A `Zotero` instance is bound to a single library. To access multiple libraries, create multiple instances.
+
+## Local Mode (Read-Only)
+
+Connect to your local Zotero installation without an API key. Only supports read requests.
+
+```python
+zot = Zotero(library_id='436', library_type='user', local=True)
+items = zot.items(limit=10)  # reads from local Zotero
+```
+
+## Optional Parameters
+
+```python
+zot = Zotero(
+    library_id='436',
+    library_type='user',
+    api_key='ABC1234XYZ',
+    preserve_json_order=True,   # use OrderedDict for JSON responses
+    locale='en-US',             # localise field names (e.g. 'fr-FR' for French)
+)
+```
+
+## Key Permissions
+
+Check what the current API key can access:
+```python
+info = zot.key_info()
+# Returns dict with user info and group access permissions
+```
+
+Check accessible groups:
+```python
+groups = zot.groups()
+# Returns list of group libraries accessible to the current key
+```
+
+## API Key Scopes
+
+When creating an API key at https://www.zotero.org/settings/keys/new, choose appropriate permissions:
+- **Read Only**: For retrieving items and collections
+- **Write Access**: For creating, updating, and deleting items
+- **Notes Access**: To include notes in read/write operations
+- **Files Access**: Required for uploading attachments

+# Command-Line Interface
+
+The pyzotero CLI connects to your **local Zotero installation** (not the remote API). It requires a running local Zotero desktop app.
+
+## Installation
+
+```bash
+uv add "pyzotero[cli]"
+# or run without installing:
+uvx --from "pyzotero[cli]" pyzotero search -q "your query"
+```
+
+## Searching
+
+```bash
+# Search titles and metadata
+pyzotero search -q "machine learning"
+
+# Full-text search (includes PDF content)
+pyzotero search -q "climate change" --fulltext
+
+# Filter by item type
+pyzotero search -q "methodology" --itemtype journalArticle --itemtype book
+
+# Filter by tags (AND logic)
+pyzotero search -q "evolution" --tag "reviewed" --tag "high-priority"
+
+# Search within a collection
+pyzotero search --collection ABC123 -q "test"
+
+# Paginate results
+pyzotero search -q "deep learning" --limit 20 --offset 40
+
+# Output as JSON (for machine processing)
+pyzotero search -q "protein" --json
+```
+
+## Getting Individual Items
+
+```bash
+# Get a single item by key
+pyzotero item ABC123
+
+# Get as JSON
+pyzotero item ABC123 --json
+
+# Get child items (attachments, notes)
+pyzotero children ABC123 --json
+
+# Get multiple items at once (up to 50)
+pyzotero subset ABC123 DEF456 GHI789 --json
+```
+
+## Collections & Tags
+
+```bash
+# List all collections
+pyzotero listcollections
+
+# List all tags
+pyzotero tags
+
+# Tags in a specific collection
+pyzotero tags --collection ABC123
+```
+
+## Full-Text Content
+
+```bash
+# Get full-text content of an attachment
+pyzotero fulltext ABC123
+```
+
+## Item Types
+
+```bash
+# List all available item types
+pyzotero itemtypes
+```
+
+## DOI Index
+
+```bash
+# Get complete DOI-to-key mapping (useful for caching)
+pyzotero doiindex > doi_cache.json
+# Returns JSON: {"10.1038/s41592-024-02233-6": {"key": "ABC123", "doi": "..."}}
+```
+
+## Output Format
+
+By default the CLI outputs human-readable text including title, authors, date, publication, volume, issue, DOI, URL, and PDF attachment paths.
+
+Use `--json` for structured JSON output suitable for piping to other tools.
+
+## Search Behaviour Notes
+
+- Default search covers top-level item titles and metadata fields only
+- `--fulltext` expands search to PDF content; results show parent bibliographic items (not raw attachments)
+- Multiple `--tag` flags use AND logic
+- Multiple `--itemtype` flags use OR logic

+cols[0]['data']['name'] = 'Renamed Collection'
+zot.update_collection(cols[0])
+
+# Update multiple collections (auto-chunked at 50)

+# Error Handling
+
+## Exception Types
+
+Pyzotero raises `ZoteroError` subclasses for API errors. Import from `pyzotero.zotero_errors`:
+
+```python
+from pyzotero import zotero_errors
+```
+
+Common exceptions:
+
+| Exception | Cause |
+|-----------|-------|
+| `UserNotAuthorised` | Invalid or missing API key |
+| `HTTPError` | Generic HTTP error |
+| `ParamNotPassed` | Required parameter missing |
+| `CallDoesNotExist` | Invalid API method for library type |
+| `ResourceNotFound` | Item/collection key not found |
+| `Conflict` | Version conflict (optimistic locking) |
+| `PreConditionFailed` | `If-Unmodified-Since-Version` check failed |
+| `TooManyItems` | Batch exceeds 50-item limit |
+| `TooManyRequests` | API rate limit exceeded |
+| `InvalidItemFields` | Item dict contains unknown fields |
+
+## Basic Error Handling
+
+```python
+from pyzotero import Zotero
+from pyzotero import zotero_errors
+
+zot = Zotero('123456', 'user', 'APIKEY')
+
+try:
+    item = zot.item('BADKEY')
+except zotero_errors.ResourceNotFound:
+    print('Item not found')
+except zotero_errors.UserNotAuthorised:
+    print('Invalid API key')
+except Exception as e:
+    print(f'Unexpected error: {e}')
+    if hasattr(e, '__cause__'):
+        print(f'Caused by: {e.__cause__}')
+```
+
+## Version Conflict Handling
+
+```python
+try:
+    zot.update_item(item)
+except zotero_errors.PreConditionFailed:
+    # Item was modified since you retrieved it — re-fetch and retry
+    fresh_item = zot.item(item['data']['key'])
+    fresh_item['data']['title'] = new_title
+    zot.update_item(fresh_item)
+```
+
+## Checking for Invalid Fields
+
+```python
+from pyzotero import zotero_errors
+
+template = zot.item_template('journalArticle')
+template['badField'] = 'bad value'
+
+try:
+    zot.check_items([template])
+except zotero_errors.InvalidItemFields as e:
+    print(f'Invalid fields: {e}')
+    # Fix fields before calling create_items
+```
+
+## Rate Limiting
+
+The Zotero API rate-limits requests. If you receive `TooManyRequests`:
+
+```python
+import time
+from pyzotero import zotero_errors
+
+def safe_request(func, *args, **kwargs):
+    retries = 3
+    for attempt in range(retries):
+        try:
+            return func(*args, **kwargs)
+        except zotero_errors.TooManyRequests:
+            wait = 2 ** attempt
+            print(f'Rate limited, waiting {wait}s...')
+            time.sleep(wait)
+    raise RuntimeError('Max retries exceeded')
+
+items = safe_request(zot.items, limit=100)
+```
+
+## Accessing Underlying Error
+
+```python
+try:
+    zot.item('BADKEY')
+except Exception as e:
+    print(e.__cause__)    # original HTTP error
+    print(e.__context__)  # exception context
+```

+
+## Other Formats
+
+Set `content` to any Zotero export format:
+
+| Format | `content` value | Returns |
+|--------|----------------|---------|
+| BibTeX | `'bibtex'` | via `format='bibtex'` |
+| CSL-JSON | `'csljson'` | list of dicts |
+| RIS | `'ris'` | list of unicode strings |
+| RDF (Dublin Core) | `'rdf_dc'` | list of unicode strings |
+| Zotero RDF | `'rdf_zotero'` | list of unicode strings |
+| BibLaTeX | `'biblatex'` | list of unicode strings |
+| Wikipedia Citation Templates | `'wikipedia'` | list of unicode strings |
+
+**Note**: When using an export format as `content`, you must provide a `limit` parameter. Multiple simultaneous format retrieval is not supported.
+
+```python
+# Export as RIS

+## Downloading Files
+
+```python
+# Get raw binary content of an attachment
+raw = zot.file('ATTACHMENTKEY')
+with open('paper.pdf', 'wb') as f:
+    f.write(raw)
+
+# Convenient wrapper: dump file to disk

+zot.dump('ATTACHMENTKEY')
+
+# Dump to a specific path and filename
+zot.dump('ATTACHMENTKEY', 'renamed_paper.pdf', '/home/user/papers/')
+# Returns the full file path on success
+```
+
+**Note**: HTML snapshots are dumped as `.zip` files named with the item key.
+
+## Finding Attachments
+
+```python
+# Get child items (attachments, notes) of a parent item
+children = zot.children('PARENTKEY')
+attachments = [c for c in children if c['data']['itemType'] == 'attachment']
+

+# Full-Text Content
+
+Pyzotero can retrieve and set full-text index content for attachment items.
+
+## Retrieving Full-Text Content
+
+```python
+# Get full-text content for a specific attachment item
+data = zot.fulltext_item('ATTACHMENTKEY')
+# Returns:
+# {
+#   "content": "Full text of the document...",
+#   "indexedPages": 50,
+#   "totalPages": 50
+# }
+# For text docs: indexedChars/totalChars instead of pages
+
+text = data['content']
+coverage = data['indexedPages'] / data['totalPages']
+```
+
+## Finding Items with New Full-Text Content
+
+```python
+# Get item keys with full-text updated since a library version
+new_fulltext = zot.new_fulltext(since='1085')
+# Returns dict: {'KEY1': 1090, 'KEY2': 1095, ...}
+# Values are the library version at which full-text was indexed
+```
+
+## Setting Full-Text Content
+
+```python
+# Set full-text for a PDF attachment
+payload = {
+    'content': 'The full text content of the document.',
+    'indexedPages': 50,
+    'totalPages': 50
+}
+zot.set_fulltext('ATTACHMENTKEY', payload)
+
+# For text documents use indexedChars/totalChars
+payload = {
+    'content': 'Full text here.',
+    'indexedChars': 15000,
+    'totalChars': 15000
+}
+zot.set_fulltext('ATTACHMENTKEY', payload)
+```
+
+## Full-Text Search via CLI
+
+The CLI provides full-text search across locally indexed PDFs:
+
+```bash
+# Search full-text content
+pyzotero search -q "CRISPR gene editing" --fulltext
+
+# Output as JSON (retrieves parent bibliographic items for attachments)
+pyzotero search -q "climate tipping points" --fulltext --json
+```
+
+## Search in API (qmode=everything)
+
+```python
+# Search in titles/creators + full-text content
+results = zot.items(q='protein folding', qmode='everything', limit=20)
+```

+# Pagination: follow(), everything(), Generators
+
+Pyzotero returns 100 items by default. Use these methods to retrieve more.
+
+## everything() — Retrieve All Results
+
+The simplest way to get all items:
+
+```python
+# All items in the library
+all_items = zot.everything(zot.items())
+
+# All top-level items
+all_top = zot.everything(zot.top())
+
+# All items in a collection
+all_col = zot.everything(zot.collection_items('COLKEY'))
+
+# All items matching a search
+all_results = zot.everything(zot.items(q='machine learning', itemType='journalArticle'))
+```
+
+`everything()` works with all Read API calls that can return multiple items.
+
+## follow() — Sequential Pagination
+
+```python
+# Retrieve items in batches, manually advancing the page
+first_batch = zot.top(limit=25)
+second_batch = zot.follow()   # next 25 items
+third_batch = zot.follow()    # next 25 items
+```
+
+**Warning**: `follow()` raises `StopIteration` when no more items are available. Not valid after single-item calls like `zot.item()`.
+
+## iterfollow() — Generator
+
+```python
+# Create a generator over follow()
+first = zot.top(limit=10)
+lazy = zot.iterfollow()
+
+# Retrieve subsequent pages
+second = next(lazy)
+third = next(lazy)
+```
+
+## makeiter() — Generator over Any Method
+
+```python
+# Create a generator directly from a method call
+gen = zot.makeiter(zot.top(limit=25))
+
+page1 = next(gen)  # first 25 items
+page2 = next(gen)  # next 25 items
+# Raises StopIteration when exhausted
+```
+
+## Manual start/limit Pagination
+
+```python
+page_size = 50
+offset = 0
+
+while True:
+    batch = zot.items(limit=page_size, start=offset)
+    if not batch:
+        break
+    # process batch
+    for item in batch:
+        process(item)
+    offset += page_size
+```
+
+## Performance Notes
+
+- `everything()` makes multiple API calls sequentially; large libraries may take time.
+- For libraries with thousands of items, use `since=version` to retrieve only changed items (useful for sync workflows).
+- All of `follow()`, `everything()`, and `makeiter()` are only valid for methods that return multiple items.

+## Retrieving Groups
+
+```python
+groups = zot.groups()
+# Returns list of group libraries accessible to current key
+```
+
+## Version Information
+
+```python
+# Last modified version of the library
+version = zot.last_modified_version()
+
+# Item versions dict {key: version}
+item_versions = zot.item_versions()
+
+# Collection versions dict {key: version}

+```
+
+**Note**: Saved search *results* cannot be retrieved via the API (as of 2025). Only metadata is returned.
+
+## Creating Saved Searches
+
+Each condition dict must have `condition`, `operator`, and `value`:
+
+```python

+
+### Create Child Items
+
+```python
+# Create a note as a child of an existing item
+note_template = zot.item_template('note')
+note_template['note'] = '<p>My annotation here</p>'
+zot.create_items([note_template], parentid='PARENTKEY')

+item['data']['title'] = 'Updated Title'
+item['data']['abstractNote'] = 'New abstract text.'

+
+# Update many items at once (auto-chunked at 50)
+items = zot.items(limit=10)
+for item in items:
+    item['data']['extra'] += '\nProcessed'
+zot.update_items(items)
+```
+
+## Deleting Items
+
+```python
+# Must retrieve item first (version field is required)
+item = zot.item('ITEMKEY')
+zot.delete_item([item])
+
+# Delete multiple items
+items = zot.items(tag='to-delete')
+zot.delete_item(items)
+```
+
+## Item Types and Fields
+
+```python
+# All available item types
+item_types = zot.item_types()
+# [{'itemType': 'artwork', 'localized': 'Artwork'}, ...]
+
+# All available fields
+fields = zot.item_fields()
+
+# Valid fields for a specific item type
+journal_fields = zot.item_type_fields('journalArticle')

+# All localised creator field names
+creator_fields = zot.creator_fields()
+
+# Attachment link modes (needed for attachment templates)
+link_modes = zot.item_attachment_link_modes()
+
+# Template for an attachment
+attach_template = zot.item_template('attachment', linkmode='imported_file')
+```
+
+## Optimistic Locking
+
+Use `last_modified` to prevent overwriting concurrent changes:
+
+```python
+# Only update if library version matches
+zot.update_item(item, last_modified=4025)
+# Raises an error if the server version differs
+```
+
+## Notes
+
+- `create_items()` accepts up to 50 items per call; batch if needed.
+- `update_items()` auto-chunks at 50 items.
+- If a dict passed to `create_items()` contains a `key` matching an existing item, it will be updated rather than created.
+- Always call `check_items()` before `create_items()` to catch field errors early.

+
+# TileDB-VCF
+
+## Overview
+
+TileDB-VCF is a high-performance C++ library with Python and CLI interfaces for efficient storage and retrieval of genomic variant-call data. Built on TileDB's sparse array technology, it enables scalable ingestion of VCF/BCF files, incremental sample addition without expensive merging operations, and efficient parallel queries of variant data stored locally or in the cloud.
+
+## When to Use This Skill
+
+This skill should be used when:
+- Learning TileDB-VCF concepts and workflows
+- Prototyping genomics analyses and pipelines
+- Working with small-to-medium datasets (< 1000 samples)
+- Need incremental addition of new samples to existing datasets
+- Require efficient querying of specific genomic regions across many samples
+- Working with cloud-stored variant data (S3, Azure, GCS)
+- Need to export subsets of large VCF datasets
+- Building variant databases for cohort studies
+- Educational projects and method development
+- Performance is critical for variant data operations
+
+## Quick Start
+
+### Installation
+
+**Preferred Method: Conda/Mamba**
+```bash
+# Enter the following two lines if you are on a M1 Mac
+CONDA_SUBDIR=osx-64
+conda config --env --set subdir osx-64
+
+# Create the conda environment
+conda create -n tiledb-vcf "python<3.10"
+conda activate tiledb-vcf
+
+# Mamba is a faster and more reliable alternative to conda
+conda install -c conda-forge mamba
+
+# Install TileDB-Py and TileDB-VCF, align with other useful libraries
+mamba install -y -c conda-forge -c bioconda -c tiledb tiledb-py tiledbvcf-py pandas pyarrow numpy
+```
+
+**Alternative: Docker Images**
+```bash
+docker pull tiledb/tiledbvcf-py     # Python interface
+docker pull tiledb/tiledbvcf-cli    # Command-line interface
+```
+
+### Basic Examples
+
+**Create and populate a dataset:**
+```python
+import tiledbvcf
+
+# Create a new dataset
+ds = tiledbvcf.Dataset(uri="my_dataset", mode="w",
+                      cfg=tiledbvcf.ReadConfig(memory_budget=1024))
+
+# Ingest VCF files (must be single-sample with indexes)
+# Requirements:
+# - VCFs must be single-sample (not multi-sample)
+# - Must have indexes: .csi (bcftools) or .tbi (tabix)
+ds.ingest_samples(["sample1.vcf.gz", "sample2.vcf.gz"])
+```
+
+**Query variant data:**
+```python
+# Open existing dataset for reading
+ds = tiledbvcf.Dataset(uri="my_dataset", mode="r")
+
+# Query specific regions and samples
+df = ds.read(
+    attrs=["sample_name", "pos_start", "pos_end", "alleles", "fmt_GT"],
+    regions=["chr1:1000000-2000000", "chr2:500000-1500000"],
+    samples=["sample1", "sample2", "sample3"]
+)
+print(df.head())
+```
+
+**Export to VCF:**
+```python
+import os
+
+# Export two VCF samples
+ds.export(
+    regions=["chr21:8220186-8405573"],
+    samples=["HG00101", "HG00097"],
+    output_format="v",
+    output_dir=os.path.expanduser("~"),
+)
+```
+
+## Core Capabilities
+
+### 1. Dataset Creation and Ingestion
+
+Create TileDB-VCF datasets and incrementally ingest variant data from multiple VCF/BCF files. This is appropriate for building population genomics databases and cohort studies.
+
+**Requirements:**
+- **Single-sample VCFs only**: Multi-sample VCFs are not supported
+- **Index files required**: VCF/BCF files must have indexes (.csi or .tbi)
+
+**Common operations:**
+- Create new datasets with optimized array schemas
+- Ingest single or multiple VCF/BCF files in parallel
+- Add new samples incrementally without re-processing existing data
+- Configure memory usage and compression settings
+- Handle various VCF formats and INFO/FORMAT fields
+- Resume interrupted ingestion processes
+- Validate data integrity during ingestion
+
+
+### 2. Efficient Querying and Filtering
+
+Query variant data with high performance across genomic regions, samples, and variant attributes. This is appropriate for association studies, variant discovery, and population analysis.
+
+**Common operations:**
+- Query specific genomic regions (single or multiple)
+- Filter by sample names or sample groups
+- Extract specific variant attributes (position, alleles, genotypes, quality)
+- Access INFO and FORMAT fields efficiently
+- Combine spatial and attribute-based filtering
+- Stream large query results
+- Perform aggregations across samples or regions
+
+
+### 3. Data Export and Interoperability
+
+Export data in various formats for downstream analysis or integration with other genomics tools. This is appropriate for sharing datasets, creating analysis subsets, or feeding other pipelines.
+
+**Common operations:**
+- Export to standard VCF/BCF formats
+- Generate TSV files with selected fields
+- Create sample/region-specific subsets
+- Maintain data provenance and metadata
+- Lossless data export preserving all annotations
+- Compressed output formats
+- Streaming exports for large datasets
+
+
+### 4. Population Genomics Workflows
+
+TileDB-VCF excels at large-scale population genomics analyses requiring efficient access to variant data across many samples and genomic regions.
+
+**Common workflows:**
+- Genome-wide association studies (GWAS) data preparation
+- Rare variant burden testing
+- Population stratification analysis
+- Allele frequency calculations across populations
+- Quality control across large cohorts
+- Variant annotation and filtering
+- Cross-population comparative analysis
+
+
+## Key Concepts
+
+### Array Schema and Data Model
+
+**TileDB-VCF Data Model:**
+- Variants stored as sparse arrays with genomic coordinates as dimensions
+- Samples stored as attributes allowing efficient sample-specific queries
+- INFO and FORMAT fields preserved with original data types
+- Automatic compression and chunking for optimal storage
+
+**Schema Configuration:**
+```python
+# Custom schema with specific tile extents
+config = tiledbvcf.ReadConfig(
+    memory_budget=2048,  # MB
+    region_partition=(0, 3095677412),  # Full genome
+    sample_partition=(0, 10000)  # Up to 10k samples
+)
+```
+
+### Coordinate Systems and Regions
+
+**Critical:** TileDB-VCF uses **1-based genomic coordinates** following VCF standard:
+- Positions are 1-based (first base is position 1)
+- Ranges are inclusive on both ends
+- Region "chr1:1000-2000" includes positions 1000-2000 (1001 bases total)
+
+**Region specification formats:**
+```python
+# Single region
+regions = ["chr1:1000000-2000000"]
+
+# Multiple regions
+regions = ["chr1:1000000-2000000", "chr2:500000-1500000"]
+
+# Whole chromosome
+regions = ["chr1"]
+
+# BED-style (0-based, half-open converted internally)
+regions = ["chr1:999999-2000000"]  # Equivalent to 1-based chr1:1000000-2000000
+```
+
+### Memory Management
+
+**Performance considerations:**
+1. **Set appropriate memory budget** based on available system memory
+2. **Use streaming queries** for very large result sets
+3. **Partition large ingestions** to avoid memory exhaustion
+4. **Configure tile cache** for repeated region access
+5. **Use parallel ingestion** for multiple files
+6. **Optimize region queries** by combining nearby regions
+
+### Cloud Storage Integration
+
+TileDB-VCF seamlessly works with cloud storage:
+```python
+# S3 dataset
+ds = tiledbvcf.Dataset(uri="s3://bucket/dataset", mode="r")
+
+# Azure Blob Storage
+ds = tiledbvcf.Dataset(uri="azure://container/dataset", mode="r")
+
+# Google Cloud Storage
+ds = tiledbvcf.Dataset(uri="gcs://bucket/dataset", mode="r")
+```
+
+## Common Pitfalls
+
+1. **Memory exhaustion during ingestion:** Use appropriate memory budget and batch processing for large VCF files
+2. **Inefficient region queries:** Combine nearby regions instead of many separate queries
+3. **Missing sample names:** Ensure sample names in VCF headers match query sample specifications
+4. **Coordinate system confusion:** Remember TileDB-VCF uses 1-based coordinates like VCF standard
+5. **Large result sets:** Use streaming or pagination for queries returning millions of variants
+6. **Cloud permissions:** Ensure proper authentication for cloud storage access
+7. **Concurrent access:** Multiple writers to the same dataset can cause corruption—use appropriate locking
+
