mzML quant error : Index was outside the bounds of the array.

Dear FlashLFQ team,

I generated a custom TSV file, according the guidelines, for FlashLFQ on mzML files, however the it keeps giving me the same error in command line and GUI:

ErrorReport.txt

My input file looks like this:

Maybe there is still a stupid mistake somewhere in my input or something?

Thanks!

Hi Patrick.

Based on the error log you provided, it seems that the .mzml file is the problem. Could you provide some more details about the how the mzml file was generated and/or send the file?

[patrick-willems]

Thanks for the fast reply. It is a mzML that is automatically generated by MSFragger during a timsTOF .d search. I saw that there was some support for Bruker data, perhaps that could be an option?

I could share the mzML in a PM if you like.

Thanks

[Alexander-Sol]

We're still experiencing some problems reading in .d files, so no guarantees.

If you could share the .mzml (and the .d file as well, if possible) via PM, I'll try to find and fix the issue.

Ok thanks! Uploading now.

Sorry to come back to this. Is there are any solution? I have also been trying to use the raw .d Bruker directories, but I get

"Error: No spectra files were found"

Although the .d files are named accordingly the File Name.

Thanks
Patrick

Thank you for your patience on this!

I took a look at the .mzML file you shared, and it appears that the file doesn't contain any MS1 scans. This would preclude analysis with FlashLFQ.

Does the .d file contain MS1 scans?

Thanks,
Alex

Thank you for the help! Sorry, I should have noticed this in the first place, I will try some other mzML conversion.

Alternatively, how can I make FlashLFQ read the .d file itself?

Thanks!
