[MINC-users] error running mincmath

[D. Louis Collins]

Haytham,

If the mincinfo output for the two volumes is the same, (ie, same 
starts, steps and number of elements _and_ same dimension ordering), 
then I suspect that the two volumes have different direction cosines.  
Check with 'mincheader file.mnc | grep direction_cosine'.

you could rerun with '-nocheck_dimensions'  - this will force the code 
to do voxel-to-voxel manipulations, without checking against the 
dimension information.
