Re: [PyMOL] Mutagenesis How many rotamers per amino acid

2010-09-16 Thread Martin Hediger
Dear All I run into something when using the Mutagenesis Wizard. Given a peptide as this: ALA-HIS-TRP, created by -A, -H, -T. After that I issue h_add to fill up valencies at the terminal carbonyl and amine sites. Say I mutate now the terminal TRP to something else (e.g. GLU), i run into a pro

Hi Martin, This took a bit of work to figure out, but the following code solves your problem (above). It will download a PDB (I coded "1RSY") and select a residue (I coded 236). I will then mutate that residue to all possible residues given what the rotamer library knows about, and write that ou

[PyMOL] set ray trace mode on different object

2010-09-16 Thread Yamei Yu
Hi all, Is there a method to set different ray_trace_mode on different object in pymol? For example : set ray_trace_mode=1 on structure while set ray_trace_mode=0 on a map? Thank you very much! Yamei Yu -- Start uncoveri

Re: [PyMOL] set ray trace mode on different object

2010-09-16 Thread Jason Vertrees
Hi Yamei, I don't think that's possible. "ray_trace_mode" is a global setting. If possible, you can try overlaying two images using different settings. To do this, render your layers and use a compositing program like "composite" from ImageMagick (http://www.imagemagick.org/script/composite.php)

[PyMOL] isosurfaces

2010-09-16 Thread David A. Horita
Hi, Is there any way to display an electrostatic isosurface (calculated by apbs) as either a nice-looking mesh or as a projection plane (as done by the SGI version of Grasp)? (Or some other format that is reasonably clear in 2 dimensions.) Thanks, David - David A.

David, Run APBS through Michael Lerner's APBS plugin. Then, for the map object "pymol-generated" click, A > Mesh and choose your isolevel; or choose A > Slice. Cheers, -- Jason On Thu, Sep 16, 2010 at 5:07 PM, David A. Horita wrote: > Hi, > Is there any way to display an electrostatic isosur
