Hi all, About 2 years ago there was a thread about using Xpress to determine peak area for label free quantification (using the -M option). {http://groups.google.com/group/spctools-discuss/browse_thread/thread/ 4503efcb3de121ae/4d7b98b5a9c6aefc?lnk=gst&q=label%2Bfree %2BXpress#4d7b98b5a9c6aefc} This work pretty well for me on the peptide level but I wonder if there is a way to use this data and get info on the protein level using the TPP (or else). The best thing would be to get this data somehow into protein prophet but if there is another way that would be great. Thanks for any help.
