{{attachment:mrclogo.gif}} = MarsBaR = [[http://marsbar.sourceforge.net|MarsBaR]] is a region of interest toolbox for SPM99, SPM2 and SPM5. It is installed at the CBU. The development version supports SPM5. To use this, start SPM / matlab on a machine that will run SPM5 (see [[CbuComputingResources#Software|the CBU computing page]]). MarsBaR should be available via the toolboxes button (let MatthewBrett know if not). You can also make MarsBaR available by manually adding the path: To do this, type the following at the matlab prompt: {{{ addpath /imaging/local/spm/marsbar/marsbar-devel-0.41 marsbar }}} to start MarsBaR. ---- = Local help for MarsBaR = Some pages showing basic steps (with screenshots) exist.

[[attachment:marsbarbatchextract.m]] : this batch takes all rois in a directory, and extracts data from all the con/beta images in another directory, saving the data to a text file. [[attachment:marsbarbatchconvert.m]] : this batch file converts rois to .nii format
