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

Sequential processing of multiple data-files in ProteinPilot

I would like to use ProteinPilot 5.0.2 to process data-sets containing 16 wiff files acquired from fractionated peptides on a 6600 TripleTOF. A Precision T7910 workstation struggles to process four files in parallel and I would like to be able to queue sequential processing of individual files overnight. I currently use the ‘LC ‘ tab to load and process individual data-files but this leads to parallel processing. Is it possible to generate 16 .group files sequentially?
