[Radiance-general] Path problem

[Greg Ward]

Hi Eshan,

Your error does not really make sense, since the first use of "split" in genskyvec happens at line 39.

I don't know why you included "filename.dat" at the end of your command, unless you wanted to redirect output to it, in which case you need to include the '>' character before it.

Finally, I believe you need to set the PATH variable to locate Radiance Perl scripts rather than simply executing them by explicit paths, because they in turn call other Radiance programs that will not be found if the PATH environment variable doesn't include the appropriate executable directory.

Cheers,
-Greg

But even adding that for the command below I get this error "Use of uninitialized value in split at /usr/local/ray/bin/genskyvec line 129, <> line 17." and some other lines of similar error.
