Which data formats are supported by this skill?

It supports a wide range of formats including h5ad, Zarr, Loom, CSV, MTX, and 10x Genomics HDF5 files.

What is the primary purpose of the AnnData skill?

The AnnData skill is designed to help users manage annotated data matrices in Python, specifically for single-cell genomics, enabling efficient storage, manipulation, and analysis of biological measurements.

How does this skill integrate with Scanpy?

AnnData is the foundational data structure for Scanpy; this skill provides the necessary patterns to prepare data for Scanpy analysis, including normalization, filtering, and dimensionality reduction prep.

Can this skill help with memory issues in large datasets?

Yes, it provides guidance on using sparse matrices, categorical data types, and 'backed mode' to process massive datasets that exceed available system RAM.
