XMAn_nonmutated_peptides

This script eliminates the hits reported from protein identification tools (proteomics) without the mutated amino acid in the sequence.

Input

  1. A file in EXCEL format (.xlsx) containing any columns but 2 columns with the exact following names: Sequence and Protein Descriptions.
    • Sequence column contains the hit sequences reported by the protein identification tool.
    • Protein Descriptions contains the descriptions of the hits and these need to include the short sequence from the XMAn.v2 headers. (e.g. GN=CDC42BPB MRCKB_HUMAN Serine/threonine-protein kinase MRCK beta|c_C3625A|p_L1209I|VGIIEGL|Missense)
