[PyMOL] Electrostatic calculations plugin for Windows?

2009-02-12 Thread Andy Torelli

Hello everyone,

	Is there a plugin similar to APBS that will work with Windows for the 
purposes of electrostatic calculations?


Thanks,
-Andy

[PyMOL] Displaying electron density from maps output by Coot.

2009-09-17 Thread Andy Torelli
Hi everyone,

I have a simple problem that has come up before (4/2/2009 post), but I 
haven't found a solution yet.
Maps written out from Coot and display in Pymol seem to be situated on 
a different origin compared to the PDB coordinates.  E.g., if I:
load my-structure.pdb
load my-map.map, map1, 1, ccp4
isomesh msh1,map1,1.0
A nice electron density map is rendered (no errors), but offset from 
the my-structure.pdb coordinates (both map and coords were output from 
Coot where they were overlaid correctly).  It sometimes works to 
explicitly indicate the residues around which to render the map:
isomesh msh1,map1,1.0,(chain a and resi 10),carve=3.0
In my current case however, an NCS-averaged map output from Coot is not 
displaying at the desired location.  To be clear, the map can be 
displayed elsewhere in space, but it does not overlap with my 
coordinates (these are not symmetry-generated molecules, they're part of 
the ASU).  As Robert Campbell indicated in response to the earlier post, 
Pymol expects maps to be calculated to cover the whole molecule of 
interest.  My question is why does this map/model pair display correctly 
in Coot while Pymol shows the map offset from the model?  Is there a way 
to tell Pymol to place the map at a different origin (i.e. so that it 
overlays with the coordinates)?

I realize this may also be a Coot question, but I'm not sure of the 
source of the problem yet so I'm posting here.  I'll try the other bb if 
necessary.

Thanks for your help,
-Andy Torelli

Warren,

Thanks for the note.  The version I had been using was version 1.0r2 
(on the lab computers).  My personal laptop is running 1.2b2.  I'll try 
there (and also upgrade to the latest-and-greatest).

Thanks for your help,
-Andy
