Anna, 

At a quick guess without seeing the files I can only guess that you
are having byte swapping problems.  Byte swapping should not ever be a
problem for MINC files but may be the case for .tag files.

To check this byte swap the files on the SUN/IRIX machine before reading ie:

   dd if=tagfile.tag of=tagfile-bs.tag conv=swab
