subprocess.py can't find the specific file

[wt163]

Did anybody have the problem with makeOctfile, After I run octfile = demo.makeOct(demo.getfilelist()), then it showed the error can't find file. Even if I have changed the Shell=True.

Traceback (most recent call last):

This is almost certainly because the RADIANCE executables are not set up on your PATH directory. Please follow the install instructions here, and particularly pay attention to setting up the PATH and RAYPATH environment variables.
