[PyMOL] Write map from list of coordinates.

Hi All-knowing Pymol'ers.

I wonder if anyone had a couple of tips/ pointers / script snippets.

I have a list of coordinates on a regular grid with associated floating point values from a calculation that I want to visualise in PyMOL. Is it nescessary to write this to an Xplor/CNS/CCP4 file format and subsequently load it, or can it be loaded directly into a map object via some fancy python code?
