advice for running DIANN for a phosphoproteome with >500 raw files
zy8281263 opened this issue · comments
Hello, we want to run DIANN for phosphorylation detection on over 500 raw files simultaneously (together as input files, had already used mscovert ), our linux has 88 available cpu cores and 1T ram, could you please give me some advice to increase the run-success rate and save the time? Thank you a lot!

Hi Yuan,
We now provide a very detailed guidance on how to use DIA-NN 1.9 for phospho https://github.com/vdemichev/DiaNN?tab=readme-ov-file#ptms-and-peptidoforms
. For now, only Windows version is available, Linux coming soon.
Best,
Vadim
Thanks for your advice, Vadim! Now, we used the DIA-NN 1.8 for phospho test on linux, the used command is here:

We are not sure if the parameter selection and settings are appropriate.
