This paper gives a step-by-step account of how to install, set up, and run MetAlign software, which can be downloaded freely (                   http://www.metalign.wur.nl/UK/Download+and+publications                                    ). The software is used for accurate mass and nominal mass data coming from different kinds of GC-MS and LC-MS platforms. The algorithms are beyond the scope of this paper and were published separately.
