[Psidev-ms-dev] referenceableParamGroup in binaryDataArray

[Thorsten S. <Tho...@an...>]

Hello everyone!

The mass spectra in my mzML file have all the same data structure:

<binaryDataArray  encodedLength="160" 
dataProcessingRef="XcaliburProcessing" >
    <cvParam cvLabel="MS" accession="MS:1000521" name="64-bit float" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000576" name="no compression" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000514" name="m/z array" 
value="" />
<binary>AAA...</binary>
</binaryDataArray>
<binaryDataArray  encodedLength="160" 
dataProcessingRef="XcaliburProcessing" >
    <cvParam cvLabel="MS" accession="MS:1000521" name="32-bit integer" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000576" name="no compression" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000515" name="intensity array" 
value="" />
    <binary>AAA...</binary>
</binaryDataArray>

Is it possible to define two referenceableParamGroup which contain the 
cvParams of both of the binaryDataArrays?

An example:

<referenceableParamGroup id="mzParamGroup">
    <cvParam cvLabel="MS" accession="MS:1000521" name="64-bit float" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000576" name="no compression" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000514" name="m/z array" 
value="" />
</referenceableParamGroup>
<referenceableParamGroup id="intensityParamGroup">
    <cvParam cvLabel="MS" accession="MS:1000521" name="32-bit integer" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000576" name="no compression" 
value="" />
    <cvParam cvLabel="MS" accession="MS:1000515" name="intensity array" 
value="" />
</referenceableParamGroup>
.
.
.
<binaryDataArray  encodedLength="160" 
dataProcessingRef="XcaliburProcessing" >
    <referenceableParamGroupRef ref="mzParamGroup"/>  
<binary>AAA...</binary>
</binaryDataArray>
<binaryDataArray  encodedLength="160" 
dataProcessingRef="XcaliburProcessing" >
    <referenceableParamGroupRef ref="intensityParamGroup"/>
    <binary>AAA...</binary>
</binaryDataArray>

In rather huge files this will save some disc space. But I do not know, 
if this is allowed.
Is it?

Thanks in advance
Best wishes

Thorsten
