[Psidev-ms-dev] Data analysis description

[Race, A. <Ala...@un...>]

Hello,
I have a question regarding recommended implementation of a full description of data analysis steps, for example. Say that I wanted to include a description of a full preprocessing workflow - how would you suggest to include the parameters related to each method? I assumed that it would be through the inclusion of additional cvParam tags, but I couldn't see anything obvious in the obo. Perhaps I am missing something?

Assuming that there are tags, then should each processingMethod tag only describe (fully) a single method and it's corresponding parameters (as below)? the example on the mzML website (http://www.peptideatlas.org/tmp/mzML1.1.0.html#processingMethod) suggests that the processingMethod tag can include a whole preprocessing workflow including multiple methods, and, the way that I see it, including parameters for each method in this situation may result in them being attributed incorrectly to a given method.

<dataProcessingList count="2">
    <dataProcessing id="preprocessing">
      <processingMethod order="1" softwareRef="test">
               <cvParam cvRef="MS" accession="MS:1000782" name="Savitzky-Golay smoothing" value=""/>
                <cvParam cvRef="MS" accession="MS:???????" name="Polynomial order" value="2"/>
                <cvParam cvRef="MS" accession="MS:???????" name="Window size" value=""/>
      </processingMethod>
                ...
    </dataProcessing>
...

Thanks for your help,
Alan
