Brian and David, Thank you for chiming in. Yes, I am aware of the "--help" option that is available. I was hoping to get a better understanding of PTMprophet in particular, so thank you for highlighting the upcoming publication. In regards to PTMProphet, I'd like to use this in conjunction with MSFragger open-search specifically. Can localization be done for the collection of mods (mass shifts) identified by MSFragger or is PTMProphet limited to a pre-defined mass shift list, in which the modifications have to be specified upfront.
I should note that I am using the Philosopher software and using PTMProphet in between PeptideProphet and ProteinProphet.
