Hello, Libra does require the mzXML file to be present (at the location specified by the base_name attribute of the msms_run_summary tag in the input pepXML file), since the reporter ion peaks need to be extracted from the spectra. I am not sure if a file with only MS2 scans will work -- I suppose it should, as long as the scan numbers correspond to the ones in the pepXML identifications. Let us know if that works!
