I agree. I think it has great potential there, as it allows for a more "physical" or "intuitive" way of manipulating the model than moving individual atoms or turning torsion angles. -- Lieven Buts Brussels Free University
RE: [PyMOL] molecular sculpting
Molecular sculpting works like a real-time energy minimizer, except that it isn't minimizing the energy. Instead, its just trying to return local atomic geometries (bonds, angles, chirality, planarity) to the configuration the molecules possess when they were first loaded into PyMOL. To actually use this feature: 1. load a PDB file 2. configure the mouse for editing (Mouse menu) or click in the mouse/key matrix box 3. select "auto-sculpting" from the Sculpting menu 4. select Sculpting from the Wizard menu 5. ctrl-middle-click on any atom in your protein to activate sculpting the green part will be free to move the cyan part will be a fixed cushion to provide context the grey part will be excluded 6. now perform any conformational editing operation in the green region such as: ctrl-left-click-and-drag on an atom ctrl-right-click on a bond, then ctrl-left-click-and-drag about that bond You can adjust the radius and cushion using the blue pop-up menus. Right now I'm not sure the sculpting feature is more than entertainment, but my expectation is that it will become part of PyMOL's crystallographic model building system in the future.

I don't know about the script or the wizard (yet), but I did try the sculpting demo in the Demo menu. You can then just drag atoms by left-clicking them while holding down the control key. The dragged atom moves, everything it is connected to is dragged along, and the structure tries to minimize its energy. Great fun! -- Lieven Buts Department of Ultrastructure Brussels Free University

[PyMOL] Molecular sculpting video
I can't find the molecular sculpting video on the home page. I have looked under "Movies" and "Gallery". Could someone point out its location to me please? Thanks, Trissa
[PyMOL] Molecular Sculpting Video
Friends, I've updated the animation on the PyMOL Web page to show a demonstration of PyMOL 0.78's new building and molecular sculpting features. Please take a look when you get a chance... http://pymol.sf.net Cheers, Warren L. DeLano, Ph.D. DeLano Scientific
