Hi Matt, I tried both SeeMS and Insilicos Viewer and I could see the spectra for individual scans. However, there was no export feature for exporting the peaks' data (mz and intensity) for the scans. What I'm trying to accomplish here is to get a peak list (all peaks rather than the base peak alone) for all the scans for a downstream manipulation. To that end, I wonder msconvert can be configured to report the peak element as numeric data instead of base64 encoded strimg. I gather this is doable because msconvert already does it for the base peak (basePeakMz and basePeakIntensity).
