  "Description": "The PSMatch package helps proteomics practitioners to\nload, handle and manage Peptide Spectrum Matches. It provides\nfunctions to model peptide-protein relations as adjacency\nmatrices and connected components, visualise these as graphs\nand make informed decision about shared peptide filtering. The\npackage also provides functions to calculate and visualise MS2\nfragment ions.",
