I wrote the first version of this program to help me search for clusters of peaks resulting from peptide fragments in Electrospray Ionization mass spectra. I subsequently expanded the program to directly interface with MassLynx, allow the user to manually edit the found ions, and finally compare the found ions with the ions predicted to be seen by hypothetical proteolysis of the protein being analyzed. The latest version helps to organize and correlate protein database search results obtained from Mascot Searching. This program is not available for download.
