Detects reliable identifications in highly heterogeneous data. PRIDE-Cluster is an online repository using spectral clustering and uses MS-Cluster algorithm. It provides two main methods to access its data by retrieving all clusters (1) that contain a given peptide identification and (2) with a consensus spectrum similar to a query spectrum.
Assists users to detect tandem mass spectra composed of chemically crosslinked peptides from those of linear peptides. xComb assigns sequence to each of the two unique peptide sequences. It combs through all theoretically feasible cross-linked peptides, to create a database consisting of a subset of all combinations represented as peptide FASTA files.
