Description

The findChromPeaks methods perform the chromatographic peak detection on LC/GC-MS data and are part of the modernized xcms user interface.

The implemented peak detection methods in chromatographic space are:

centWave

chromatographic peak detection using the centWave method. See centWave for more details.

centWave with predicted isotopes

peak detection using a two-step centWave-based approach considering also feature isotopes. See centWaveWithPredIsoROIs for more details.

matchedFilter

peak detection in chromatographic space. See matchedFilter for more details.

massifquant

peak detection using the Kalman filter-based method. See massifquant for more details.

MSW

single-spectrum non-chromatography MS data peak detection. See MSW for more details.
