I was wondering if anyone running X Tandem searches through TPP has been 
able to include spectra with > 3+ in the search output.  My mzXML files are 
from an Orbitrap analyses and I have verified that MS2 spectra were 
acquired for >3+ charge states.   I am specifying the following command in 
the X Tandem parameter file:

<note type="input" label="spectrum, maximum parent charge">5</note>

However, after the database search, when I inspect the resulting pep.xml, 
all the spectra with > 3+ are removed (about 5% of the total scans). Many 
of them meet the minimum required peak count threshold, so I'm not sure why 
they aren't being passed into the final output.  If anyone has encountered 
this issue and has found a solution, please let me know.
Thanks,
Todd
