Thanks for the information. The real problem is that a single computer generates working-mzXML files for some wiff files but not-working files for other wiff files. (not only on different computers). For the empty scans, the working-mzxml file generated on a different computer (for the same wiff file) does have a non-zero peaksCount and proper information for the particular scan.
I want to import this mzXML file into mzmine but it reports errors for the "corrupt peak" and refuses the import. Any suggestions will be appreciated.
