gPPI toolbox use create_sphere_image erro
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

RE: gPPI toolbox use create_sphere_image erro
Hi Lanbo,
The error message simply means that your VOI from create_sphere_image extends beyond the first-level mask (mask.img or mask.nii). Can you send me the 2 VOI image files. If they are truly the same, then this would indicate a bug in the program.
However, I suspect the VOIs are different in their location.
Best,
Donald
