Hi, Just to add to Ulrich's message: Xpress and ASAPratio values also are not parsed into iProphet.pep.xml and in general it seems that the current viewer not fully adjusted for iProphet output (or maybe the other way around). Like Ulrich, I'm also using iProphet to combine results from different search engines - in the current pepXML output there are 2 probabilities pepP (which seems like the highest PP probability found for duplicated peptides) and iP (which I assume is the one to follow), but I can't see the sensitivity and error curves of either of them and "more_pepanal.pl" output is just a single line with the location of the iProphet.pep.xml file. I also wonder which of one of the probabilities is used and reported by the "Calculate Statistics" option. I'm using TPP v4.3 JETSTREAM (unstable dev prerelease) rev 0, Build 200903041031 on Mac with OS 10.5.6 but saw similar output on RPP v4.2 on PC with winXP. Thanks, Oded
