Pete,
All my experience with HDF has taught me to avoid the old-style DFSD
interface like the plague. Does your graphics package read the new-style
HDF4 scientific datasets? If so, I'd try everything to make a file in that
format. Can you elaborate on the problem with dimensions in the new format?
Cheers,
Liam.
