XCMS / Alignment of matrices with obiwarp
I usually perform the feature extraction from HRMS data with software from the vendor and want to use the XCMS package in R now to align the features from different measurements.
As i already have all of the required information available in matrices (one matrix per sample measurement with the mass, retention time and intensity), i would like to know if i can perform the alignment now directly on the matrices without using the typical input formats for XCMS (NetCDF, mzData,...).
Best regards,
Sascha
