[Psidev-pi-dev] [HUPO-PSI/mzIdentML] How to use MS:1001239 (frag: immonium ion) to annotate immonium ions on specific amino acids? (#9)

[Harald B. <not...@gi...>]

What is the intended use of MS:1001239 (frag: immonium ion) and how can this be used to annotate immonium ions on specific amino acids?

Here's what we currently do in the PeptideShaker mzIdentML export using the outdated PRIDE CV terms:

<IonType charge="1" index="4 5">
   <FragmentArray measure_ref="Measure_MZ" values="120.0808411"/>
   <FragmentArray measure_ref="Measure_Int" values="14483.125"/>
   <FragmentArray measure_ref="Measure_Error" values="6.53397579810644E-5"/>
   <cvParam cvRef="PRIDE" accession="PRIDE:0000244" name="immonium F"/>
</IonType>

How would the same be done with MS:1001239 (frag: immonium ion)?
