it could be that the info needed to create the orientation info is not
in the dicom. You can also try it without the -it dicom. You can also
specify an orientation like --in_orientation RAS. This will probably be
wrong, but it will at least let you see the image.

Dear Dr Bruce,
Thank you very much for your response.
I tried
mri_Convert -i INPUT_FIRST_DICOM -it dicom -ot nii -o OUTPUT_4d.nii
The problem is when I run mri_info on the "OUTPUT_4d.nii" I get the
following
voxel-to-ras determinant 0
ras to voxel transform:
mat =NULL!
MatrixFree: NULL mat POINTER!
I am not sure what I am doing wrong. So thank you for help
Jon
