Matlab: Robust Toolbox 1.3
This set of functions is intended to run 'random effects' analyses using iteratively reweighted least squares (IRLS), a model fitting technique that is less sensitive to outliers than ordinary least squares (OLS).
 You must have the statistics toolbox (sorry!)
 This software is compatible with output from SPM99, SPM2, SPM5 or in general programs that write Analyze contrast images
 Works on any platform, in Matlab. Unzip to use, and put the folder on the Matlab path
