If you are running MSQuant version 1.4a10 or higher (up to
1.4a12) u can get an error message when opening the
protein validation window or when conducting quantitation
of LTQ-FT data. If this error says that it cannot recognize
the spectrum type (and thereby shows your spectrum
header) plz read below:
MSQuant looks for spectrum header "tags" which enable it
to recognize the spectrum type. This is defined in the
spectrumClassification.xml file. If your LTQ-FT ICR source
is recognized as "NSI" (spectrum header something
like: "FTMS + p NSI Full ms"), then you are forced to
correct the ion source type in the
spectrumClassification.XML file. U can do so by opening
the XML file in a text editor (e.g. notepad) and simply FIND
AND REPLACE "ESI" with "(ESI|NSI)" [or just replace it
with "NSI" instead of "(ESI|NSI)" ]
I have uploaded the spectrumClassification.XML file which
is correct for LTQ FT ICR ms with an NSI and/or ESI
source along with this message.
For questions just mail me...
