Topic: Copare Peaklists with Excel Data

Hello, I want to compar my spektra with an excel Folder of masses. Is this possible? I have this problem because I could not manage to cut my protein in a defines way. So I made a list with all possible proteinmodifications and now I compare my spectra with this list manual. Is there an other way to solve this Problem?
Thank You

Hi,
1) how do you want to cut your protein, that it is not possible with mMass?
2) you can define a custom Compound database with your peptides and use the Compound Search tool

You can also edit your local definition of chymotrypsin cleavage or you can define your own enzyme.
