ColorizeMS

ColorizeMS is a Java application that allows to qualitatively compare up to three experimental conditions measured via hyphenated mass spectrometry (MS).

Single hyphenated MS datasets can be visualized as contour plots. The intensities measured for individual ion channels at individual mass spectral scans can be represented using a color mapping as shown in the following image.

In this example, the retention time of the measurement is mapped to the x-axis and the mass-to-charge ratio is represented on the y-axis. In GC- and LC-MS measurements the time axis is discretized by the scan rate of the instrument. Each scan is represented in this visualization by one pixel and the discretization of the mass-to-charge ratio is done by rounding to nominal masses and binning the measured intensities.

ColorizeMS provides functionality to compare measurements from up to three experimental conditions and rapidly visualize qualitative differences. ColorizeMS is realized as web-start application which has been tested on Microsoft Windows, Mac OS X, Linux and Solaris . The project is licensed under the GNU Public License 3.0.
