Actually I just looked at the ENVI help file and apparently the menu
option you were using is for "Landsat 7 fast" (not 7A) ...I wonder if
your file being 7A makes a difference?

I have worked with Landsat maybe twice in my life, but I'd have
thought the way you were trying to open them was the way to go too.
Did you try the other landsat file options? I seem to recall there
being a lot more landsat file choices than there are now (ENVI 4.2/
IDL6.2) maybe they've stopped supporting some?

Well, I'm *trying* to use ENVI. At the moment, I'm
not having much luck. :-(

Apparently (I discovered this accidentally), instead of opening
the band files directly, it is necessary to open a file that
has the letters "hrf" before the .fst file extension. This file
opens in ENVI, and from there you can access the bands. Go figure.

Cheers,

David
