Interesting. That appears to be a bug in the config file reader. Until it gets fixed, use the command-line equivalent for filters, i.e.
--filter "analyzerType ITMS" --filter "polarity negative"

Hi Matt. I used a configuration file (-c) containing the following
information

outdir=Z:\Toxikologie\MSconvert\negmzXMLfiles
mzXML=true
32=true
filter="analyzerType ITMS"
filter="polarity negative"

for the version, it is the one contained with ProteoWizard release
2.1.2596 (ProteoWizard MSdata 2.1.2595, ProteWizardAnalysis 2.1.2587).
Is it the information that you need? Thanks for your help

What was your exactly command-line and which version of msconvert did you use?

Hi,

I am using msconvert to transform my .raw file acquired on a LTQ Velos
into mzXML file. I performed LC-MS measurements in positive/negative
mode in a single run, therefore my files contain both ion trace (i.e.,
positive and negative). I am trying to extract from my .raw file the
negative ion trace and convert it in mzXML (filter="polarity
negative"). When I am doing that, msconvert ignore my filter (it wrote
back Ignoring wrapper: ) and transform my raw data into mzXML file
which contains the negative and positive ion trace. Does anybody know
how to extract each ion trace separately?

thanks a lot for your help, C dric
