Hi Gary,

I was trying to run DTI_TK and encountered following error message at
the diffeomorphic registration stage:

template dimension 2 not an integer powers of 2
size is currently determined internally.
vsize = 1, 1, 1
origin is currently default to [0, 0, 0].
outFile = s05_spd_aff_to_mean_diffeomorphic_initial.5.df.nii.gz
cannot open s05_spd_aff_to_mean_diffeomorphic_initial.5.pwa

Is there a requirement on the dimensions of the volume? "dimension 2"
means y axis? Currently my dimensions are 256 X 256 X 49 by 1.0 X 1.0
X 2.0. Is it complaining about 49?

Could you shed some light on this? Thanks a lot!

Best,
Nagesh

Hi Nagesh,

Yes, the template needs to be first resampled that way. "dimension 2" means the z axis, since c/c++ indexing from 0.
