Could you change the RAM (GB, 0=auto) to a non-zero value such as 64, and try again?

Thanks,

Fengchao

I run it only with non-zero value (tried 100 and 128 GB - 128 GB is what we physically have). Should I try auto?

Your computer may not have 100 GB free memory if the 128 GB is the total size. Could you try 64 and 0?

Thanks,

Hi @fcyu ,

Sorry for the delay with the response - I'm using a shared workstation and it took a little longer to find a slot to try 64 or 0.

With 64GB, the outcome is exactly the same - FragPipe crashes with the same error file in the bin folder (attached).
With auto RAM (0), the problem moved to the earlier steps and frapipe failed to check spectral files (log attached)

JVM started with 1 GB memory

I think something was wrong in your command because

JVM started with 1 GB memory

C:\Users\workstation_user\Desktop\Oleg\FragPipe-jre-22.0\fragpipe\jre\bin\java.exe -jar -Dfile.encoding=UTF-8 -Xmx1G C:\Users\workstation_user\Desktop\Oleg\FragPipe-jre-22.0\fragpipe\lib..\tools\MSFragger-4.1\MSFragger-4.1.jar C:\Users\workstation_user\Desktop\Oleg\LFQ_output_27_percolator_try10\fragger.params ....

It seems that you only got 1 GB memory.

Best,

I'm using a GUI, so I'm not sure what went wrong. I've tried to start the analysis a few more times and each time -Xmx parameter was different (although much higher, e.g., 75, 116, 106 G).
With 'Auto' and 116GB assigned, it seems working. Now, I wonder how to make it reproducible if each time it sets -Xmx some "random" numbers.

Something was messed up. Please double check the FragPipe and system configuration

1. You set the RAM to 0 because there is workflow.ram=0 in your log file.
2. FragPipe detected that there was 1 GB free memory because there is -Xmx1G in your log file.

Best,

Fengchao
