Title: export pseudospectrum?
Post by: cbroeckl on August 17, 2011, 03:24:39 PM
Is it possible to export a text formatted pseodospectrum?  I am interested in trying CAMERA's grouping functions as an alternate to AMDIS.  Having a text export option would potentially allow to integrate CAMERA output with NIST/custom database searches.  Thanks.

There is a pseudospectrum export function in CAMERA. The function getpspectra(object, grp) extract from a xsAnnotate object a specific group. The output is the same as getPeaklist, which contains only the selected pseudospectra. This output can be processed further.

Does that answer your question already?
If not, how should the export look like?

Thanks Carsten,

This did answer my question.  I don't know exactly what format I need yet, but just good to know that there is a function to get this data out.  On a related subject - when CAMERA is selecting spectra for plotting pseudospectra, what is this selection process based on?
