for each selected mass window,
eicmatrix calculates EICs of
every raw file and combines them together. It is recommended to
correct the retention time first using
eicmatrix(xs, xy, center)
table including mz location parameters
file number which is used as a template for retention time correction
For each detected mass, an extracted ion chromatogram (EIC) is calculated. In order to determine the elution time for each detected mass, the EICs of every mass are combined between all acquired runs.
Make sure that xcms-retention time correction (centwave) was applied to the dataset. The output will be a matrix of EIC's
