One more problem, meaning the other one was solved, or this is
an additional problem?
So what are those "I*" images, Dicom?
What is one example of a full file name?
What is the output of the to3d command?
What is the output of 3dinfo on the AFNI dataset?
Note that 'to3d' does not re-orient data at all. It can only be
confused about that the current orientation actually is. If those
are not ANALYZE images but Dicom, they should be fine.
Note that there may be a variable in SPM that switches the left and
right directions (neurological and radiological orders, or some
such names).
