PSMatch

PSMatch helps proteomics practitioners to load, handle and manage Peptide Spectrum Matches.

Key Features:

• Peptide-protein relation modeling: Models peptide-protein relations as adjacency matrices and connected components.
• Graph visualization: Visualises peptide-protein relations as graphs.
• Shared peptide filtering: Enables informed decision making about shared peptide filtering.
• MS2 fragment ion calculation: Calculates and visualises MS2 fragment ions.
• MS2 scan annotation: Annotates and visualises MS2 scans in conjunction with the Spectra package.

Scientific Applications:

• Peptide spectrum match management: Loads, handles and manages Peptide Spectrum Matches in proteomics workflows.
• Proteomics identification data exploration: Explores proteomics identification data through relation modeling and visualization.
• MS2 data analysis: Calculates fragments and annotates MS2 scans for downstream proteomics analysis.

Methodology:

Models peptide-protein relations as adjacency matrices and connected components, with graph-based visualization.
