Hello, we're studying organisms that has a general O-glycosylation system that targets a specific three amino acid motif. The regex for this motif would be D[ST][AILVMTSGCF] where it's the S or T that's glycosylated. I'm now wondering what the best approach to add this rule would be? Is it possible to use some sort of regex in FragPipe for glycosites? Thanks in advance!

Best, Dennis
