Dear Mike, You can at least do the following:
*** first call of command *** - parse the file - store the data in an object (dictionary, list, etc.) - you can probably store the Strings that make up the CGO object. - refine the data using the cutoff - create CGO object from refined data *** second call of command *** - delete CGO object - refine the data using the cutoff - create CGO object from refined data Message: You can create objects in Python scripts that are persistent as long as PyMOL is running. This should work a lot faster than parsing the file several times. Kristian > What I want to do is parse a file that has a bunch of coordinates and draw > the spheres in PyMOL.
