Permissions Denied for Output Dir

[Rankicker795]

Would it be possible for make_GLM_grids.py to not have output dir be required? Everytime I try running it on my Mac, it keeps throwing a Permissions Denied to the default output directory structure no matter where I put it or how open I set the permissions for the directory.

Since the -o argument is not required, do you mean that it always tries to write a file even without that argument?

I had never thought of running the script without saving output, so this is an interesting case to think about handling.
