AnnSQL

AnnSQL enables SQL-based queries on AnnData objects, leveraging an in-process DuckDB engine for significant performance enhancements in large-scale single-cell genomics analysis.

Key Features:

• SQL-based querying: Enables parsing of single-cell genomics datasets using SQL syntax on an AnnData-inspired database structure.
• In-process DuckDB engine: Constructs an AnnData-inspired database using the in-process DuckDB engine for order-of-magnitude performance improvements.
• Minimal computational resource requirements: Executes operations on million-cell datasets in minutes on a laptop without requiring high-performance computing clusters.

Scientific Applications:

• Large-scale single-cell RNA-seq analysis: Processes atlas-scale single-cell and single-nucleus RNA-seq datasets on personal computers.
• Single-cell genomics atlas analysis: Supports complete single-cell workflows across various genome-wide measurements.

Methodology:

AnnSQL constructs an AnnData-inspired database using the in-process DuckDB engine.
