This is a technical question. I have a real-space representation of a potential in a grid of points, however I have the grid in the format:
x y z w v
meaning: the coordinates of each point, the weight and the value of the potential.
I would like to visualize this potential but I need to re-write this potential in a cube file. I haven't found any particular software or script to do that.
I know how to get the header of the cube file. However I don't know how to re-write the points.
Is there a specific format to write the points?
