The Cell Annotation Platform (CAP) is a community-driven platform for creating, exploring, and storing cell annotations. It provides infrastructure to accumulate, share, and analyze annotation terms with associated molecular signatures to interpret cellular identities, encouraging researchers to converge on consensus nomenclature.
The platform requires .h5ad AnnData files formatted according to a standard schema. The required fields are defined in CAP-AnnData-Schema.
- CAP AnnData schema
- CAP documentation - general project documentation
- CAP upload validator - a Python package that automatically validates whether a provided AnnData file follows the CAP schema.
- CAP Seurat Converter - an R tool that converts CAP-published files into Seurat v5 objects.
