Introduction
MathDAMP facilitates the visualization of differences between metabolite profiles acquired by hyphenated mass spectrometry techniques. Differences are highlighted by applying arithmetic operations to all corresponding signal intensities from whole raw (automatically preprocessed and normalized) datasets on a datapoint-by-datapoint basis. The results are visualized using density plots. More...
MathDAMP requires Mathematica to run. Trial version of Mathematica can be downloaded from Wolfram website.
