Hi - I don't know why you've got this error, but it is unlikely to be due to
the voxel size. The tractography works fine on anisotropic voxels, although
I wouldn't recommand it because one direction (z here) is averaged over a
longer distance, which could be misleading in the process of estimating the
pdf on diffusion directions.
