Yes, I second this. The program HDFRead you found on my web page
is *not* designed to read any HDF file, but just the one created
with HDFWrite. You can use the HDF_BROWSER if you have to, to
learn the name of your cloud_fraction variable, then use Liam's
routines to read the data you need from your files.

Cheers,

David
