Oliver, The Xpress chromatogram viewer lags Xpress in functionality and because of this, can report a different ratio. There was functionality added to Xpress which impacts the chromatogram reconstruction, such as the -p isotope option, which never made it to the Xpress viewer. So both tools can be reconstructing the chromatograms using different settings, hence the different numbers. I believe that using "-p0" in the Xpress options will cause the ratios calculated in Xpress and shown in the viewer to be the same. Otherwise there is no other solution/workaround until some work is put in to resolve this discrepancy. Maybe someday I'll feel guilty and work on this when I have some free time but that hasn't been the case for years now and this is simply a low priority issue for me personally.
