Hi Yee-Soon,
And one more thing, since i'm using Thermo QqQ to collect my data under parent
ion scan mode, do u mind to tell me what's the parameter range for example, the
mass tolerance (either m/z or ppm) or the noise signal. It is a bit complicate
and i'm a new user to MZmine. I believe the default parameters are subjected to
QTOF since Dr Oresic research group mainly used mainly QTOF for their research.
Or may be you can tell me how purpose of each of these parameters since not
much details been written on MZmine manual.
I am afraid your question is too general.
The parameter values need to be optimized according to the characteristics of
your own data. Please observe your spectra carefully to determine what is the
typical mass error (for m/z tolerance) or intensity level of noise. If you
still have problems, please write a more specific/detailed question.
Best regards,
Tomas
