Hydroxy proline diagnostic ion error #2324

Closed trishorts closed 9 months ago

trishorts commented 9 months ago

Ben Orsburn in his proteomics news blogpost highlighted an error in the reported mass for the diagnostic ion of hydroxyproline. Turns out we had the erroneous mass in our mods list. This PR updates the mass of the diagnostic ion to the correct value of 171.0764 which comes from C7 H11 N2 O3+ as reported by Dr. Frey.
