OK , more troubles.I found the README file with "The most important program to learn......", changed directory to /opt/Radiance3.8a/ray/obj/misc and tried running % rad -o x11 daf.rif. The result was: rad Command not found.My environment includes: RAYPATH=/usr/local/lib/ray and PATH=/usr/bin:............/usr/local/bin/rayX11 is running. When I look at these directories ( /usr/local/lib/ray and /opt/Radiance3.8a/ray )they are full of files. I'm sure everything installed properly. It seems that the "rad" command does not exist or something is not pointing in the right direction. Sorry for the frustrations.Bill Rock

This means it's not in your $PATH or not on your system at all.
My environment includes: RAYPATH=/usr/local/lib/ray and PATH=/usr/bin:............/usr/local/bin/ray
This suggests that all your Radiance binaries are installed in /usr/local/bin/.
Can you find a file /usr/local/bin/rad? (just try 'ls -l /usr/local/bin/rad')
It does not matter where the binaries for Radiance are installed as long
as you have the directory path in your PATH environment variable. If everything
is installed in /usr/local/radiance3.8/ you need an entry for $PATH like
'/usr/local/radiance3.8:/usr/bin:...'. Typically the application specific
directories are first in the list, followed by the general system directories.
RAYPATH is used by Radiance internally. If a file can not be found immediately
in the current scene directory. I don't have it defined on my system and
Radiance works fine (it may be essential for the first example scenes you'r
going to use, though!).
X11 is running. When I look at these directories (/usr/local/lib/ray and /opt/Radiance3.8a/ray )they are full of files.
As far as I can see '/opt/Radiance3.8a/ray' is not in your PATH (I assume you
didn't delete anything that is directly related to Radiance.) Path names
on Unix systems are case sensitive, btw.
Please look for the directory that contains 'rad', 'rpict' and 'rtrace'.
This directory is where all your executables are installed and this should
be in your PATH.
BTW: You can always run a program with the full path
(i. e. '/opt/Radiance3.8a/ray/bin/rad scene.rif') but that's neither convenient
nor will it help you if a Radiance binary is called from within a scene
file.
