Re: gridtocube.py

You can find the utility at the bottom of http://molcas.org/download.html

There is no guarantee it will work. It worked for me when I wrote it, for what I needed it... With recent GRID_IT versions you way need to add the NoLuscus keyword.

Can you please explain why is it?

Re: gridtocube.py

Could be a bug in the script or an unsupported format in the grid file.
