[Feature Request] Sage output as a pepXML file

[sciordia]

I would like to import the results obtained with Sage into the Trans Proteomic Pipeline (TPP). I want to create a spectral library from the results but I would need the Sage output as a pepXML file. Would it be possible to add this export option in Sage, please?.

Thank you very much.

Best regards, Sergio

Hi Sergio,

I'm not really interested in supporting any additional XML based formats (it's 2024) directly in Sage. It should be possible to write an adaptor in python/R that takes the existing output files and maps them to whatever format you need!

Thank you very much for your answer @lazear, maybe you are right but pepXML is still a very common format and almost all programs work with it. It is the usual format for TPP, mokapot, etc. In any case, as you say, I will try to convert the TXT output file from Sage in R to pepXML, I hope to get it.

Thanks again for your time.

Best regards, Sergio

I'm happy to add a link to your tool in the Sage README if you put it on Github!

I hacked something very quick and dirty to convert Sage output to mzIdentML to work with some of the TPP and other tools that consume mzIdentML. It is not 100% schema-valid mzIdentML, but then again, this is true for most software that produce output in this format.

Thanks - I can add a link to it. There is an old branch in this codebase for producing mzIdentML (could probably be revived), but it's a quite tricky format and can take a long time/lot of space to generate... and I also found issues in that some consumers of mzIdentML actually reject the standards-compliant version (tested against the reference tool) that I produced.
