chromatograms

Kendrick has taught Ophelia to read and mark DNA chromatograms.

The red line is the TIC for the chromatogram, while the black lines are the extracted ion chromatograms of individual m/z ion peaks in the mass spectral dimension, and, only of peaks detected using XCMS using the new centWave method by Ralf.

So, I reran the centWave peak detection with 750, 1000 and 1250 ppm, and that indeed make XCMS recover many more metabolites, and, also important, with more extracted ion chromatograms per metabolite, yielding a more accurate mass spectrum.

This long tail of ion chromatograms is what I am interested.

Sequence chromatograms were analyzed using Sequencher, v4. 8 (GeneCodes, Ann Arbor, MI).
