[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 [wiki: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-0.41 marsbar
to start MarsBaR.
