Export Scene, Mesh Surface, wrl

Dear Chimera, I would like to export a scene of 1PRH (PDB of Cyclooxygenase) with a surface mesh, in wrl format for import into Cinema4D. (Screen shot attached) I am able to import scenes with ball and stick, sphere, solid surface, ribbons etc, in this way without problem. However, the mesh doesn’t seem to be in the wrl file once imported. The ribbon is there, but the mesh is not, or the mesh is not imaging for some reason. Am I missing something, or missing a step? Thank you so much for your assistance in advance, Kind regards, Cynthia Turner

Running out of memory when recording movies
by Oliver Clarke 01 Feb '16

Hello, I am consistently running out of memory when recording long-ish movies (using the Animation tool) on a Macbook pro with 16GB RAM. Admittedly there are a lot of atoms in the model I am using (~120,000), but most are not displayed (only ribbons). Chimera is consistently crashing at about the 300 frame mark and looking at the activity monitor during the recording I can see memory pressure gradually increasing until Chimera freezes (which is generally not recoverable). Is there any way to reduce the amount of memory required for movie recording? Will deleting all undisplayed atoms help? Is there some way to perform these operations on disk rather than in memory (most likely a silly question)? Cheers, Oli.

Morph groups of maps?
by Oliver Clarke 01 Feb '16

01 Feb '16

Hello, In a situation where I have maps for two conformations, and I've extracted out domain specific maps in both cases, is it possible to run morph maps on both groups of maps simultaneously? Or is there any way to apply color zone to the trajectory generated by morph maps? I would like to generate a morph map movie where the map is colored by domain throughout the morph, and can't figure out how to do so. Cheers, Oli
