Dear CCLer,

Would you please give me some suggestions on the peptide database =
screening? what's kind of peptide databases available? and which docking =
program is good at the peptide VS?  (FTDock? GRAMM? or small ligand =
docking program such as DOCK, AutoDock?)

Thank you very much for your help!

Dear Marco,

Don't forget that the Olson laboratory now distributes AutoDock for
Windows using Cygwin (www.cygwin.com, a free Unix-like system for
Windows) as well as a Windows version of AutoDockTools (ADT). ADT is
the GUI that lets users set up AutoDock runs, launch them, and analyse
the results graphically.  There are many molecular graphics options,
too, thanks to its foundations of PMV, Michel Sanner's Python
Molecular Viewer.  We now distribute a Tutorial for ADT, along with
sample files, to help you get started.

Of course, AutoDock and ADT are also available for many other
platforms, including Mac OS X, Darwin, Linux, Solaris, and IRIX.

We have also processed the National Cancer Institute's Developmental
Therapeutics Program's Diversity Set into a format that can be used by
AutoDock.  These consist of 3D structures generated by Prof.
Gasteiger's program CORINA, and then converted using AutoDockTools
into PDBQ format with all rotatable bonds defined and partial atomic
charges computed, using Gasteiger's PEOE method: these are the charges
we used in callibrating AutoDock 3's empirical free energy function.  
Most of the 1990 compounds passed our quality tests, but there are
about 7% that did not.

We will be releasing the NCI Diversity Set for AutoDock as soon as
possible.  Watch http://www.scripps.edu/pub/olson-web/doc/autodock for
news when this will be available.

Dear Eike!

The volume by Klessinger and Michl has a Section 1.2 where the use of 
molecular orbital (MO) models in the description of electronic 
transitions is explained: 

Martin Klessinger, Josef Michl: "Lichtabsorption und Photochemie 
organischer Molekuele", VCH 1989, ISBN 3-527-26085-4

Later editions and in English are available. - Basically, equating a 
molecular orbital energy difference to an electronic excitation 
energy is wrong, primarily for two reasons:

1)
The energy required to promote an electron from MO i to MO j is not 
equal to the energy difference e(j) - e(i).  The promotion energy 
E(i-->j) can be expressed as   

  E(i-->j) = e(j) - e(i) - v(i,j)

where the term -v(i,j) represents the interaction between a hole in
orbital i and an electron in orbital j.  This term may be relatively
small if the two molecular orbitals are spatially separated, but in
general, v(i,j) amounts to several electron volts and is by no means
negligible.

2)
The wavefunction |i-->j> of an excited electronic configuration is not
in general a good approximation to an eigenfunction of the
many-electronic Hamilton operator H.  Generally, matrix elements
corresponding to <i-->j|H|k-->l> are not close to zero.  Hence,
excited configurations tend to interact, and a proper description must
include Configuration Interaction, (CI).  Of particular importance is
the first order CI between near-degenerate configurations of the same
symmetry, f.inst. for alternant hydrocarbons where it gives rise to
"plus" and "minus" states. - Inclusion of multiply excited
configurations (like i,k-->j,l etc.) in the CI formally accounts for
electronic correlation effects, thus leading to a description going
beyond the orbital picture.  However, semiempirical CI-procedures
(PPP, CNDO/S, INDO/S, ZINDO, etc.) usually limit the CI expansion to
singly excited configurations, and account for correlation effects by
empirical adjustment of parameters in the models. 

Yours, Jens >--<

Dear All,

I am using Gaussian98 to run population analysis calculations on whether MP2
or B3LYP optimised structures. For each method  I would like to get the
density which is available with MP2 using Density=MP2 or current. For DFT,
it seems that the density is calculated using the SCF procedure. Does anyone
know if it uses the results of Kohn-Sham, or if it is calculated from HF
ones. In other words is it the "true " dft density that we get ?
If it is not, is there any other way to get it ?
Many thanks for your help.

Carole,

Yes this will be the DFT density.

Hello, CCLers:

     Does anyone have any specific book references that deal with
computational modelling of crystals and solids? The more detailed,
the better!

Thanks,

Dear All,

Could someone explain the error message generated by PC GAMESS? The program treats molecular symmetry in a strange way: it produces new atoms as if Unique Atoms were only presented while full molecular frame is really given.

	Attached is an example of the Furan molecule (9 atoms, 6 Unique Atoms, C2v (i.e. Cnv  2) group of symmetry).

Dear All..

Someone knows as can be runed gaussian98w
under the interface MS-DOS of a PC?

I tries the following alternative:

g98 < file.gjf > file.out
g98w < file.gjf > file.out

but no works

Some suggestions?

Thanks in advances for your kind replies.

Just try the following command
c:\g98\g98.exe file.gjf

The output file will be "file.out"

Note that this will work only under Windows, in DOS box,
not in native DOS.
