Qun, This is something that is easist to do with the Fitting wizard. Starting with the ATP, click successive matched pairs of atoms in the ATP and then the ADP. When you have enouch pairs, click Fit. That should be all you need to do. Cheers, Warren -- mailto:war...@delsci.com Warren

RE: [PyMOL] Showing electrostatics on surface ?

2004-07-06 Thread Warren DeLano
Vladimir, Michael and I have been working on streamlining the process for using ABPS with PyMOL and are almost at the point where PyMOL can generate the necessary PQR file (for proteins at least) from an ordinary PDB file lacking hydrogens, c-terminal carboxylates, etc. PyMOL can also

RE: [PyMOL] questions about electrostatics

2004-07-06 Thread Warren DeLano
Qun, PyMOL doesn't (yet) have the ability to calculate Possion Boltzmann electrostatic potentiallys. You'll need to use an external tool like GRASP or APBS to perform that task. If spectrum b doesn't produce the desired result, then there is probably some strange B-value present

[PyMOL] New Beta with Vacuum Electrostatics (for proteins)

2004-07-08 Thread Warren DeLano
PyMOLers, Electrostatics purists will undoubtedly question the wisdom of this action, but in the latest Windows beta version of PyMOL, I have added an experimental and as-yet-unvalidated automatic way to calculate and display vacuum electrostatic potentials (computed with a constant homogenous

RE: [PyMOL] selecting residues around

2004-07-10 Thread Warren DeLano
Jason Ah, I found the problem: Sticks represent bonds, not atoms. Normally, in order to see a bond, *BOTH* atoms involved have to have either sticks or lines shown. That's why you weren't seeing anything until increasing the radius of the selection sphere, which included the first bond atom

[PyMOL] PyMOL 0.96 Released

2004-07-12 Thread Warren DeLano
PyMOLers, The official 0.96 version of PyMOL had been released. As you've likely come to expect, this isn't so much a formal release as a quality-controlled build containing many of the recent beta features. Of greatest interest will probably be: 1) The sequence viewer. 2) Built-in support

Ian, Yes, I have gotten PyMOL to work with the laptop version of this display (just Windows so far). The stereo effect is quite good. However, your head does need to be in just this right spot in order to get the effect. After 15 minutes, I learned to do this automatically, moving slightly off

RE: [PyMOL] Measuring Angles

Anthony, New in version 0.97 is a get_angle function that takes three single-atom selections. There is also a get_distance that is more efficient than the distance command (which creates objects)... See help get_angle To set up a loop, you'll need to generate a list of selections # for

That's good advice, except that you'll lose any bonds between the two selections... the following example will keep those bonds (by duplicating atoms) create protein2, (selection_1) create protein3, ((not selection_1) extend 1) set line_width=1.2, protein2 set line_width=2.0, protein3 Cheers,

Ben, Thanks for the great benchmarks! PyMOL is definitely showing non-linear behavior when it comes to loading a lot of objects...I don't know why this is exactly, but I can tell you that I didn't originally envision (and thus optimize PYMOL for) loading of so many objects. As it currently
