# w4mcorcov_galaxy_wrapper Planemo-based galaxy-tool-wrapper to wrap a SIMCA® OPLS-DA® S-PLOT® "work-alike" tool. This tool plots the correlation of each feature with the OPLS-DA projection of multivariate data for two classes of data against the covariance of the same. The original plot which this tool emulates is described in: > Wiklund, Susanne and Johansson, Erik and Sjöström, Lina and Mellerowicz, Ewa J. and Edlund, Ulf and Shockcor, John P. and Gottfries, Johan and Moritz, Thomas and Trygg, Johan (2008).
