No IMS model ran mzML input

[patrick-willems]

Hey,

I was eager to test the new ims model on some of our data. I use MS2-only mzML files that contain ion mobility fields as:

<cvParam cvRef="MS" accession="MS:1002815" name="inverse reduced ion mobility" value="1.1835660934448242"/>

After succesfully running sage, the PIN and TSV outputs the ion_mobility, predicted_mobility and sqrt(delta_mobility) columns all default to zero for all PSMs. Do we need to specify another JSON parameter or the info might not be correctly parsed from the mzML?

Thanks!

Can you share which converter you used, and the mzML for the full spectrum (or the whole file)? I am going to guess that this has to do with IMS being written to different parts of the XML document by different converters.

These files were converted by MSFragger. The gzipped mzML can be downloaded via: https://filesender.belnet.be/?s=download&token=0f657e1d-ea0c-4c75-8b89-227cf2d1394c

ok ... the issue is that I was expecting the 1/k0 info to be inside the selected ion info

              <selectedIonList count="1">
                <selectedIon>
                  <cvParam cvRef="MS" accession="MS:1000744" name="selected ion m/z" value="720.3768122581744" unitCvRef="MS" unitAccession="MS:1000040" unitName="m/z"/>
                  <cvParam cvRef="MS" accession="MS:1000041" name="charge state" value="1"/>
                  <cvParam cvRef="MS" accession="MS:1000042" name="peak intensity" value="5823.0" unitCvRef="MS" unitAccession="MS:1000131" unitName="number of detector counts"/>
                </selectedIon>
              </selectedIonList>

whilst in your data it is located in the scan info

          <scanList count="1">
            <scan>
              <cvParam cvRef="MS" accession="MS:1000016" name="scan start time" value="19.516155242919922" unitCvRef="UO" unitAccession="UO:0000031" unitName="minute"/>
              <cvParam cvRef="MS" accession="MS:1002815" name="inverse reduced ion mobility" value="1.2539584636688232"/>
              <cvParam cvRef="MS" accession="MS:1000512" name="filter string" value=""/>
              <scanWindowList count="1">
                <scanWindow>
                  <cvParam cvRef="MS" accession="MS:1000501" name="scan window lower limit" value="199.143798828125" unitCvRef="MS" unitAccession="MS:1000040" unitName="m/z"/>
                  <cvParam cvRef="MS" accession="MS:1000500" name="scan window upper limit" value="1539.11572265625" unitCvRef="MS" unitAccession="MS:1000040" unitName="m/z"/>
                </scanWindow>
              </scanWindowList>
            </scan>
          </scanList>

... I think according to the current mzML specification both are viable annotations, it is both a:

1. ion mobility attribute -> scan attribute
2. ion selection attribute.

The solution would be to copy the content here:
https://github.com/jspaezp/sage/blob/a7414c8bcf608c5b5ff5271c08d1f5d87d72c23b/crates/sage-cloudpath/src/mzml.rs#L241-L243

to this line as well ...

IN THE MEANTIME you can pass the .d directly! (if you have one ...)

Thanks for the help! I can work with this.
