PETRA: Multivariate analyses for neuroimaging data

In last years, many research eorts in neurosciences have focused in multivariate approaches based on machine learning as an al- ternative to the use of Statistical Parametric Mapping and the univariate analyses that it provides. However, this relatively new eld still lacks of a software framework that completely meets the needs of the scientic community. In this work we present a toolbox designed to facilitate the access to the recent advances in neuroimaging data analysis based on multivariate approaches. The toolbox, written on Matlab, is freely avail- able and implements a Graphical User Interface that allows managing neuroimaging data in an easy way.
