Hi Nitrc community,

When use a mask created by create_sphere_image to be as VOI to run PPPI. Error come with 'VOI has 123 voxels in 2x2x2 space. VOI is larger than dataset. Program will exit'. But when I use traditional way make a VOI.mat, it work, the command says  'VOI has 123 voxels in 2x2x2 space VOI has 123 voxels in 2x2x2 space. This is in the the same space as the input data and functional mask.'
They both use same SPM.mat.

Looking for your replay.

Thanks,
Lanbo
