I got some trpysin digested peptides for a protein for which I used PREGO. I got directed to a webpage which has given scores and ranks for each of my peptides. Can you tell me what the scores and the ranks are about? Are they giving any information about the detectability of the peptides in a mass spectrometer? I got the following output from PREGO.
Rank Sequence Score
1 GGLDLR 0.16867737160352636
2 GDLSLR -0.06754151848263762
3 GESLFQGR -0.17631845487837808
4 GEPLQVER -0.6208215989137332
5 TLIYYLDEIPPK -0.9140796672874998
I am new to proteomics and it would be really helpful if you guys could help me out :)
