Dear pymol users, I'm trying to create a movie, using lsqman and pymol, of a molecule of ~1700 residues (HETATMs deleted, no hydrogens, alternative conformations removed). I created 60 pdb files with lsqman and loaded them (as different states of the molecule) into pymol. In the default "lines" representation, pymol plays all right through all 60 frames. However, as soon as I try a more fancy representation ("sticks" or "cartoon"), pymol runs out of memory, recommending to "reduce the quality, size, or complexity of the scene" (this is on Linux, pymol svn revision 4037, on a Core2 Duo, NVIDIA Quadro, 4 GB RAM). From what I read, people created movies of the ribosome using pymol, so ~1700 residues should not be a problem, right? I tried reducing the viewport to stamp size (120 x 240), to no avail. Which other settings should I check in order to "reduce quality, size, or complexity"? I would be grateful for any hints on how to get this going.
