Now, now.
I just tried this. To make it work, I had to add another
step. I used the HDF_Browser to look at the HDF file.
This produced a "template" structure, which I had to pass
to HDF_READ. This returned another structure, but at least
this structure had a field with my SDS in it. I pulled that
out and it went into Insight slick as a whistle.
My guess is that you were trying to import one of those
intermediate structures and that Insight was looking at you
as if you hadn't any. :-)
Cheers,
David
