Hello All, We have some Thermo QExactive derived RAW files where the MS1 was acquired in PROFILE mode and the MS2 is centroided. I want to convert it to the MGF format in centroid mode> Can I choose peakPicking option to "Vendor MsLevel=1-" or do I've to specify "Vendor MsLevel=1-1" to convert the MS1 scans to profile mode explicitly? Thanks

While converting an MGF to mzXML, the Precursor intensity and m/z info. doesn't seem to get separated and reported as : <precursorMz precursorIntensity="0" precursorCharge="1">7202.379928 279560768.000000</precursorMz> While in the original MGF file it was as follows: BEGIN IONS TITLE=TDS virtual parent no.0 PEPMASS=7202.379928 279560768.000000 CHARGE=1+ I guess this is the way it should lookin the converted mzXML : <precursorMz precursorIntensity="279560768.000000" precursorCharge="1">7202.379928</precursorMz>...
