Developers:
I am trying to convert a nifti formated image to the mgz format using mri_convert, but there is an error stating that the time units are unknown. Since there are only 3 dimension, the time dimension should not matter.
mri_convert -it nii -ic 128 128 128 -oc 128 128 128 -iid 1.0 0.0 0.0 new_all.nii new.mgz mri_convert -it nii -ic 128 128 128 -oc 128 128 128 -iid 1.0 0.0 0.0 new_all.nii new.mgz reading from new_all.nii... niiRead(): unknown time units in /Users/hjmjohnson/src/regressiontest/SGI/MR/B2-downsampled/TEST/20_ACPC/harr is/new_all.nii
Any help would be greatly appreciated.
Thanks, Hans
PS: Here is a dump of the nifti header that I am trying to use:
~/src/deleteme/utils/nifti_tool -disp_hdr -infile new_all.nii
header file 'new_all.nii', num_fields = 43
