I calculated the electron density and electrostatic potential of 2 amino 
purine using Gaussian 94. I would like to visualize them. Does somebody 
know any software for Linux that can do that? I am also interested if 
somebody did the same thing so that I can compare the results. If yes, 
can you please give me the reference?
Thanks a lot,

Hello:
       I want to learn theory as well as practical examples of Autodock. I 
did go through Manual but I need some more detailed and user friendly 
tutorial using, which I can practice whole docking. Please suggest me some 
good reference or source of tutorial for AutoDock.

Thank you,

Deepangi

In practice "electron correlation" is a term to describe the inadequacies of
the Hartree-Fock (single determinant) model.  
 
The best way I can describe the physics is that in the Hartree-Fock model,
the repulsion energy between two electrons is calculated between an electron
and the average electron density for the other electron.  What is unphysical
about this is that it doesn't take into account the fact that the electron
will push away the other electrons as it moves around.  This tendency for
the electrons to stay apart diminishes the repulsion energy.

Dear CCLers,
I need to perform calculations on molecules containing Rubidium using
Gaussian 98 using 6-31G*.
As the 6-31 G* basis set is missing for Rubidium I would like some help to
find references, web sites or, even better, the basis set itself.
May I thank you in advance for your help.

Greetings:
	If you do modeling of materials or device design in the field of integrated optics, please consider presenting a talk or poster at Photonics West 2003.  To save space, I will only post the part of the Call pertinent to modeling:

The goal of this conference is to provide an interdisciplinary update and review of innovations in IO materials, devices and applications, manufacturing technologies, and theoretical and experimental tools that support these innovations. The conference includes, but is not limited to, the following topics (WG: waveguide, IO: integrated optics, NL: nonlinear):
* Theory and Modeling:
Numerical modeling methods and design tools
Novel IO devices
Propagation phenomena in special WG structures (e.g., photonic band-gap structures)
Optical guided-wave circuit design
Etc.

	If you would like a full version of the "Call for Papers", or if you have any questions, please let me know.

Sincerely,

Travis Thoms

Hello:
After going through Archives of CCL ,I feel you all can help me. I have just 
started using AutoDock 3.0 and I am starting with HIV gp120 and small 
molecule for docking. Please suggest me sources, references in which basics 
and applications of AutoDock with reference to HIV gp120 or protein and 
small ligand is discussed.

Thank you very much,

Deepangi
