Peptide Hit Results Processor
The Peptide Hit Results Processor can be used to convert an X!Tandem results file (XML format) or a SEQUEST Synopsis/First Hits file to a series of tab-delimited text files summarizing the results. When parsing X!Tandem data, the program will insert modification symbols into the peptide sequences for modified peptides. Parallel files are created containing sequence information, modification details, and protein information. The user can optionally provide a modification definition file that specifies the symbol to use for each modification mass.
The "Data Extraction and Analysis for LC-MS Based Proteomics" sessions at the 2007 and 2008 US HUPO conferences discussed the use of the Peptide Hit Results Processor for processing X!Tandem results. PDF files of the slides presented are available for download as a 5 MB PDF file (2007) and a 6.5 MB PDF file (2008).
Note that you can generate SEQUEST Synopsis/First Hits files from SEQUEST .Out files using the Peptide File Extractor.
Please see the Command Line Application Help page for additional information on running this program at the Windows command prompt.
