PhosphoScore software interface

PhosphoScore is a phosphorylation assignment program that is compatible with all levels of tandem mass spectrometry spectra (MSn) generated through the Bioworks/Sequest platform. The program utilizes a “cost function” which takes into account both the match quality and normalized intensity of observed spectral peaks compared to a theoretical spectrum.

Technical Details -

PhosphoScore was written in Java. The program is accessible through a graphical user interface (GUI) or can be run from the command line. The input directory should contain all Sequest DTA and OUT files as well as the Sequest parameters (sequest.params) file from the original LC-MSn analysis. Data from different MS levels should be analyzed separately by PhosphoScore due to differences in Sequest search parameters. Please consult the "readme.txt" file for more details on running the program. For a complete description of the software, please see Ruttenberg et al. J Proteome Res. 2008 Jul;7(7):3054-9.
