Thank you for your response and your example!
It works as advertised.
However, from what I understand, in your example, you use the -geomparent on TT_N27_junk_8.nii.gz to get the slice thickness, etc for the file to be created. I do not have this file. I only have my ascii files and I know that my values are correlations and of dimensions 50 x 61 x 23 with voxel dimensions : 3.5 x 3.5 x 6 (mm). How do I get this information in?
Let me know if I am not explaining myself.
Many thanks and best wishes,
Ranjan
