The grassp (GRaph-based Analysis of Subcellular/Spatial Proteomics) python module enables fast, flexible and scalable analysis of subcellular proteomics datasets.
It uses the anndata format to store mass-spec data and analysis results and scanpy for many of the dimensionality reduction and visualization functions.
grassp enables
- Reading the ouput format of most mass-spectrometry search engines (using protdata)
- Calculating subcellular enrichment profiles of proteins for different experimental protocols
- Annotating the subcellular location of proteins in an unsupervised and semi-supervised manner
- Detecting proteins at the interface of organelles
- Detecting multi-localizing proteins (work in progress)
- Detecting re-localizing proteins between conditions (work in progress)
- Combining multiple subcellular proteomics datasets
- Assessing subcellular resolution
- Finding the optimal experimental design for future experiments based on simulations
- Integration of multiple modalities (e.g. Lipidomics) (work in progress)
Please refer to the documentation for reference to individual functions and tutorials.
