[Radiance-general] error message "file coeff_perez.dat cannot be opened"

[Thomas Bleicher]

Hi Sotiris.

How did you install Radiance/gendaylit?

If you are on Linux and used a recent Debian package then see here:

http://www.radiance-online.org/pipermail/radiance-dev/2011-January/001093.html

The package maintainer forgot to include the file in the package. You can
try to install an older package or use the source from the official website
(see below).

If you use another system (OS X or Windows) you should check that your
RAYPATH environment variable is set. Then check that the file is not in the
folders listed in RAYPATH.

If you are sure that you don't have the file grab the Radiance source code
from here:

http://www.radiance-online.org/software/rad4R0all.tar.gz

Extract the archive, search for the file and place it in one of the folders
listed in your RAYPATH. That should do it.

Regards,
Thomas
