Hi Christian,
Looks like there is no -Xmx
flag for Crystal-C. @chhh Can you help to add it to FragPipe?
The optimial peak threshold is decided during the parameter optimization step in MSFragger. You can see a table in the consol after mass calibration.

Do we even support crystal-c for TimsTOF when using .d?

Hi @anesvi
He/She is using mzML converted from .d. I think Hui-Yin test a little bit using a mzML from timsTOF months ago.

Hi,
Yes, I think it's good to add -Xmx (as Fengchao suggests) to FragPipe. Thanks.

I don't remember why it wasn't there in the first place, but I'll add it to the next release

Fixed.
Dear FragPipe-Team,
I'm currently trying to process PASEF-data (converted to mzML with MSconvert with activated "combine ion mobility" option) with OpenSearch parameters (default settings). I'm using a Xubuntu 18.04.4 LTS machine with 32 cores (x86_64) with 200GB RAM. After successful MSFragger search (pepXML and corresponding tsv files are generated) FragPipe crashes at the Crystal-C step.
I guess, there is a problem with the allocated heap size, because the RAM usage I've observed during the process wasn't higher than 120GB. I've tried to run the Crystal-C command now on the command line with all available RAM allocated (-Xmx181G) and it seems to run smoothly.
Did I do something wrong during the setup of the FragPipe run, or is this this missing parameter during Crystal-C invocation a FragPipe bug?
By the way, when I've used PASEF data converted to mzXML with the "threshold peak filter" option set to 150, this problem did not occure... Related to this: I've just read your new paper on Biorxiv and now I'm wondering where you see the optimal "peak threshold" parameter? Is it 100 (as default by FragPipe) or 150 (as in your paper) or are reasons to go higher / lower?
Thanks again for your help. Best, Christian
