Vendor specific software / Excalibur: Exporting exact mass list.
I am trying to export an exact mass list for direct infusion data using the Q-Exactive.
If I go to export: Clipboard: Export: Clipboard (Exact Mass)
the m/z is off even after setting 5ppm and .xxxx decimal places in the Mass Options.
For example I get:
89.059671   3189961.5
89.059471   3031701.75
89.05987           2126474.25
89.059272   1919686.5
... etc.
When these should all be one mass.
So I thought of a few methods:
Maybe convert my data from profile to centroid:
I was having trouble as the centroid option is not showing up for me.
Maybe go to View: Spectrum List
and then
Display Options: All Peaks
But this doesnt give all peaks... for example in a wide m/z range it gave peaks up to about 2000 intensity, and than in a narrower range it gave peaks up to an intensity of 10.
Any help would be greatly appreciated

Other / Re: Converting LCMS profile data to centroid?
Hello I have the same problem.
Right click Display Options, over the mass spectra, go to Labels, and select centroid.
Sadly the centroid option doesnt show up for me so I cant test this (even though I have profile data).
Then you can probably right click, export, write to RAW file.
Let me know if that works.
