My first thought was that you're setting the offset value incorrectly,
but its going to be hard to help you with this b/c there's no way we
can tell if those keywords are set to the correct value, since we know
nothing of the image you're opening. Here are two general suggestions
though:

1) Try opening the image using the GUI, maybe saving it out to a
temporary file, and seeing what kind of header ENVI creates for it.
Then you'll have an idea what the header values should be, assuming
ENVI opens it correctly.

2) Instead of using ENVI_SETUP_HEAD, use ENVI_OPEN_FILE. You won't
need to know all the header values with that command, and in fact
after you open the file you can use ENVI_FILE_QUERY to get the header
values.

Cheers,
Jeff
