Create an mzML file

Description

Writes an mzML file having chromatograms and their native IDs.

Usage

createMZML(ropenms, filename, XICs, transitionIDs)

Arguments

filename	(string) name of the mzML file to be written. Extension should be .chrom.mzML.
XICs	(list of list of data-frames) list of extracted ion chromatograms of all precursors.
