| The problem comes when we try to render the results from this | analysis. We consistently get: | | >> ???

The obvious thing is | the presence of an explicit mask but I don't understand why this | would prevent us from rendering our results. Can anyone shed some | light on this? I can't fully figure this one out. The error message occurs because spm_slice_vol is trying to resample a 12 x something matrix (because the mex files still support the old handles that spm_map_vol used to generate). I'm guessing that one of the dimensions of your results is 12 voxels. I guess I'd better drop supporting the old-style volume handles now.
