Error running post_processing.py – 'Namespace' object has no attribute 'shading_path'

[kegalas]

Description:
When I run:

python post_processing.py -i ~/rawdata -n 7 -e ~/env_illu.mat -d 1.0

the script crashes with:

AttributeError: 'Namespace' object has no attribute 'shading_path'

I see that the variable shd_mat is used for the rawlike computation, but the README doesn’t explain where to obtain a shading.mat file or how it should be generated. Could you please clarify how is shd_mat produced?

Thanks in advance!
