scverse/anndata
Annotated data.
Provides an in-memory and on-disk data structure optimized for annotated matrices with sparse data support, lazy evaluation, and PyTorch integration. Bridges pandas and xarray by combining observation/variable metadata with multi-dimensional arrays, efficiently handling large single-cell omics datasets. Serves as the foundational data container for the scverse ecosystem, particularly Scanpy.
