MassChroViewer is a data viewer for liquid chromatography (LC)–mass spectrometry (MS) data. LC-MS data in mzXML or mzML format are visualized in two-dimensions by retention time (RT) vs. m/z and the peak positions extracted using data processing software can be overlaid. A mass ruler function to evaluate mass accuracy and adduct assignment, immediate colour strength change to view peaks in wide intensity range and MS/MS visualization tool will help assess the quality of raw and processed data. A database search tool linked to a mass substructure calculator is used to metabolite annotations.

A PC (64 bit, > 4GB RAM is recommended) with Java Runtime Environment (JRE 64 bit, version 1.7 or later) is required to run MassChroViewer. See Oracle's website for installation of Java.
We tested the tool using following PCs:
Windows10, MacOSX 10.9.5 and CentOS7.2 Linux
