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.

Thanks,
Paul
