ProteinPilot phosphopeptide library and DIA-NN

ProteinPilot phosphopeptide library and DIA-NN

I have prepared a spectral library for a phosphopeptide enriched sample and I am generating my SWATH samples from similarly enriched samples. The problem is that when I use DIA-NN for the retention time alignment and quant, it doesn’t recognise the terminology of the spectral library annotated by ProteinPilot. DIA-NN recognises Unimod:21 for phosphorylation, but PP uses phospho(Tyr) etc. Other than changing the data dictionary to get around the mismatch, anyone have any suggestions for how I might resolve this? Thank you, Roz
