Analysis of O-glycoproteomics data with MS-Decipher, MetaMorpheus, MSFragger-Glyco and Mascot


ABSTRACT: We presented a user-friendly proteomic database search platform, MS-Decipher, for the identification of peptides from MS data. Two scoring schemes, rank score and hyperscore, could be used for peptide spectra matching. FDR controlling strategies could be used after searching, and it was found that MS-Decipher performs well compared to traditional database searching software. In addition, a special search mode, O-search, is presented to search O-glycopeptides for the O-glycoproteomics analysis. Data and result files in several formats could be used in searching and validation. Dataset of tryptic peptides from serum were used to evaluate the performance of our software in analysis of O-glycoproteomics . The searches using the same parameters were also performed by other commonly used software, like MetaMorpheus, MSFragger-Glyco and Mascot, to compare the performance.
