adjustRtime: Alignment: Retention time correction methods.

Description Author(s) See Also


The adjustRtime method(s) perform retention time correction (alignment) between chromatograms of different samples. These methods are part of the modernized xcms user interface.

The implemented retention time adjustment methods are:


retention time correction based on aligment of features (peak groups) present in most/all samples. See adjustRtime-peakGroups for more details.


alignment based on the complete mz-rt data. This method does not require any identified peaks or defined features. See adjustRtime-obiwarp for more details.
