Thanks for the thorough explanation.
I agree that this logic works quite successfully. At least in my hands, the
data from LTQ without charge information work as well as these from
orbitrap, in terms of protein ID.

When a precursor charge is not known, the logic that is used to
analyze the data is as follows. If there are no peaks above the
precursor m/z then the spectrum is assumed to be 1+ and analyzed as
such. If there are peaks above the precursor m/z then the precursor
ion is assumed to be multiply cha
Hello:
I collected some data from LTQ XP and converted them to mzXML by ReAdw.
I noticed there is no precursor charge information, unlike the data from LTQ
Orbitrap.
Nevertheless, it seems X!tandem can still get it right. So i become very
curious how it handles the charge.
Does anyone know?
