Hi Nick, Brendan et al.,
Wishlist item: It would be nice to have an identifier for transitions that are diagnostic of fragment ions containing a specific PTM, i.e. some sort of flag or column that can be sorted and filtered in the document view grids and indicates those transitions that are diagnostic for a PTM (i.e. all y ions greater than the position of the PTM in question from the c terminus and all b ions greater than the position of the PTM in question from the N terminus, etc.). Having such an identifier would help a lot in automating the process of finding diagnostic transitions for PTMs and save a lot of time by not having to do this manually. Perhaps there is already a way to do this and I am just missing it.
Thanks for considering this wishlist request,
Dietmar
