cosmiq - COmbining Single Masses Into Quantities
Description
cosmiq is a tool for the preprocessing of liquid- or gas -
chromatography mass spectrometry (LCMS/GCMS) data with a focus
on metabolomics or lipidomics applications. To improve the
detection of low abundant signals, cosmiq generates master maps
of the mZ/RT space from all acquired runs before a peak
detection algorithm is applied. The result is a more robust
identification and quantification of low-intensity MS signals
compared to conventional approaches where peak picking is
performed in each LCMS/GCMS file separately. The cosmiq package
builds on the xcmsSet object structure and can be therefore
integrated well with the package xcms as an alternative
preprocessing step.
