Thank you for the very clear explanation. I was just a bit confused about how many proteins you can quantify and instead how many can be significantly different. After your confirmation that all the parameters that I used were correct I will look more into details of my data. Do you know if there

Without looking at your data directly it is hard for me to comment on the quality of the results. It sounds like everything is working correctly. The reduction in the protein count when you filter by ASAPRatio p-value is to be expected since p-value represents a likelihood that a given protein's

I forgot, another little question: at the end of the protProph analysis I can't see the protein name (but can see just the accession number) when I work with the IPI database; while I can see everything correctly if I use for example the UniprotKB database. Is there some parameter to change in the

Hi David, yes I analysed quite a big set of data (16 LC runs) and it seems to work. But I have to look better into the results. The first thing that impressed me is that after I analysed and validated this set of data, the output of proteinProphet is more or less 1000 proteins (after setting min p

Hi Federico, Your parameter set looks correct. Have you tried to execute to program with this set of params? Did it seem to work? -David On Mon, May 18, 2009 at 6:32 AM, fto...@gmail.com wrote: > > Hope not to be too annoying cause I am really enjoying this toolbox > but I have always lot of
