Re: [Psidev-ms-dev] TraML ion m/z and TraML::id attribute

[Matthew C. <mat...@va...>]

In our CV, the m/z term is a unit, not the name of the measurement. If 
you recall, we had the same problem in mzML. We solved it by making 
specific terms with m/z in the name, but not the whole name. So it 
should be:

<CvParam cvRef="MS" accession="xxx" name="<some kind of> m/z" value="862.9467" unitCvRef="MS" unitAccession="MS:1000040" unitName="m/z" />
