the protein FDR filter didn't reach the desired threshold, try a higher threshold using the --prot parameter

[jjjjjj17]

Hello!! I have a problem running my data, can you help me find out why? Here is the log file log_2024-07-29_23-45-15.txt

[dpolasky]

From the log: time="23:45:15" level=error msg="the protein FDR filter didn't reach the desired threshold, try a higher threshold using the --prot parameter"

It looks like you have millions of "proteins" in your fasta file, and it was not possible to filter the results to achieve a 1% protein level FDR. You can try setting a higher protein FDR threshold as suggested. It is an unusual fasta file, so your search may need special handling - but it's hard to say without knowing more about your search and data.

I saw similar errors several times before, and it seems to be a Philosopher bug. I always wanted to test or let someone take a look at this bug. Let me transfer it to Philosopher repository to keep track of it easier.

Dear Fengchao,

I also get this error with my data. It is a DIA-speclib workflow run.

Could it be because some of my samples (25 overall, 24 DIA, and 1 DDA for spec library generation) have low identifications? But most samples have decent identifications. I'm not expecting too many because these are immunoprecipitation samples.

Any ideas?

I attach the filter.log file.

Thanks,

I can provide mzML files, if needed.

yes please, and it would be more helpful if you can directly provide the .pep.xml files with this error.
