Dear colleagues!
I'm not professional in quantum chemistry.
I did local optimization in g03 and gamess (us) many times. As I understood global geometry optimization (finding the geometry with global energy minimum) was not implemented in these programs ( I mean Monte Carlo methods, genetic algorithm, etc.). Is there any program in quantum chemistry that can do such kind of optimization?
I browsed the net and found many articles about this topic but not implemented algorithm.
Thanks a lot!

No, I don't think so.
This is because quantum-chemistry is so time-consuming that it often
is worthwhile to use human intelligence (aka chemical intuition). So,
what you could do is generate a number of different conformations (I'm
assuming here that you have a floppy molecule) at a low-level (MM or
semi-empircal), and then reoptimize at a higher-level QM.
I've used Spartan in the past, and that program did have such an option.

Hi,
doing a global optimization by mean of quantum mechanic methods might be
very time consuming. Probably it could be better performing a
conformational search by molecular mechanics and then perform geometry
optimization of all conformers within a certain energy treshold by mean
of a quantum chemistry method.
Regards,
Alessandro Contini

Dear All,
I tried to use the orbitals generated by Jaguar (writted in *.gau file) in a Gaussian job, but all my attempts were unsuccessful: a Gaussian job terminated with an error "Unable to orthonormalize Vectors". I tried several basis sets (TZV or LACVD), but got the same message from Gaussian. I don't understand the reason of that. I used ip160=4 and ip104=9 in gen section of Jaguar's input file, and made 1 SCF (igonly=1) or a few SCF cycles. The resulting orbitals were used by Gaussian by specifying guess=cards and (in case of LACVD) pseudo=cards. I would be very gratefull if you could give a comment on this.
Thank you in advance,
Katerina

Hi,
Warm wishes to everyone..
Our group is planning to purchase a new hardware (probably CRAY CX1 supercomputer). We essentially use Sybyl, Schrodinger etc..
I will sincerely appreciate sharing your experience with CRAY CX1, positives and negatives and suggestions before purchasing..
Is there any other brands or combination of features giving superior performances ?
My ultimate goal is to get comprehensive idea/recommendations to buy a powerful, hassle-free high performance computer (super-computer ?).
Thanks in advance for sharing your valuable experience.

Hi Patris,
NICS is indeed available with gaussian (see keyword NMR in the
manual). I'm afraid HOMA, FLU and PDI are not available as a direct
output of gaussian.
For HOMA you may easily write a small program to calculate its values
or even do it by hand; you just need geometry and a set of parameters
(see for instance Chem. Rev. 101, 1385).
For FLU and PDI you will need gaussian wave function file (check for
out=wfn keyword in gaussian). In addition, you need another program to
read this file and calculate the atomic overlaps. From these atomic
overlap files you can calculate FLU or PDI indices.
This program will help in the last step:
http://iqc.udg.edu/~eduard/ESI/
There you will also find a manual which explains how to do these
calculations, and there are few links to free programs to calculate
atomic overlaps.
Hope this helps,
Eduard

Spartan has had it for many years, but I think it's only
for conformation search, ie "bonds" can't be broken or formed
during optimization. VASP can do simulated annealing in a
general way, I suppose in principle it could work for anything.
We used shell scripts to combine our "Taboo Search" code with
G03 and VASP and do global optimization at DFT level (see PRA 79 (2009)
043202 and 043203 for recent applications). Ours is a research code still
under development --- not user-friendly, not well supported, and
only works for clusters --- but if you're interested, let me know.

Hi Sangeetha:
Adding missing residues before simulation is an important task and
people have their own preferences about the methodology. You could try
the free program SWISS PDBViewer/DeepView program (Link 1) and follow
the second link which explains the procedure with help of tutorials
listed on the second link

Thanks for fast reply!
Could you advice me this kind of software (MM) for quick coarse search of
local
minima. I know about Hyperchem in my opinion it works slow.
As count of local minima rises exponentially with system size
could you advice me such kind of software which can be used on
high-perfomance computers, supercomputer
(preferably using MPI parallelization).
Thanks a lot!

Hi,
doing a global optimization by mean of quantum mechanic methods might be
very time consuming. Probably it could be better performing a
conformational search by molecular mechanics and then perform geometry
optimization of all conformers within a certain energy treshold by mean
of a quantum chemistry method.

Hello,
I do not think that a viewer program is a good choice to add missing
residues to a protein. It is a loop modelling task, which can be done by
homology modeling softwares, try Rosetta commons or Modeller, both are free
for academics.

For molecules, there are more builders (or programs that contain a builder) than
you can shake a stick at: Molden, ECCE, Maestro (free for academics), Arguslab,
to name a few free ones.
For periodic systems, it's not so rosy. I generally use gdis
(http://gdis.sourceforge.net/). I wouldn't use it to build a complicated
structure from scratch, but you can add atoms by a mouseclick and drag them
around on the screen, create a supercell, cleave a surface by specifying the
Miller indices, etc.
More powerful, but with a steep learning curve (which I haven't yet found the
energy to master) due to the lack of a GUI is tetr
(http://www.cmmp.ucl.ac.uk/~lev/codes/lev00/).
A commercial product I haven't used, and don't know the price of, is
Crystalmaker (http://www.crystalmaker.com/).
You are right about Materials Studio. It's the best, but their "academic
pricing" is based on the wrong meaning of "academic" :-).
What doesn't improve things is that each of them supports a few file formats,
but it's always the wrong ones, and Babel isn't that good at periodic
structures either (no VASP, no SIESTA, no CASTEP).
HTH,
Herbert
