New upgrade for CAChe WorkSystem Users!

Users of the CAChe Worksystem, BioMedCAChe, and Quantum CAChe, etc. can now
upgrade to the latest version of MOPAC2009 with
PM6<http://cacheresearch.com/brochures/MOPACbrochure.pdf>.
MOPAC2009 handles many more elements than MOPAC2000; a total of 69 for PM6,
42 for AM1 and PM3, and 15 lanthanide sparkles, while PM6 provides
significantly improved accuracy over the older methods.  Existing CAChe
procedures for the old PM5 method in MOPAC2000 automatically use the new PM6
method in MOPAC2009 (PM5 is replaced by PM6 in MOPAC2009).  "MOPAC2009 for
CAChe" is developed by Stewart Computational Chemistry LLC, USA which has no
relationship with Fujitsu Ltd, Japan, the owner of the CAChe products.

Dear Roby
According to your Route Section, you have asked for one layer calculation u=
sing b3lyp/genecp. The problem is returned to defining the keywords and bas=
is set.
You have to change your route section to:

# opt=3Dmodredundant oniom (b3lyp/genecp:uff) geom=3Dconnectivity

-----------------------------------

Sorry, but you said you have Gold in your system, I couldn't see it when yo=
u defined the ECP basis set.
I have another comment, why do you use UFF force field? think twice before =
using it.
Check your system again.
Sincerely;

Hi,

I was trying to optimize a Gold compound (Gold bonded to glutathione) using=
 ONIOM. There are two levels of theory being used, B3LYP/6-31+g(d) for high=
er layer and UFF for lower layer. I have defined Gold atom using LANL2DZ-EC=
P.

Now the calculation has converged but all atoms (including those were in lo=
wer mechanics layer) ended up in upper(quantum) layer.

The input I gave was
# opt=3Dmodredundant oniom (b3lyp)/genecp geom=3Dconnectivity

(Name)
(Molecular defenition in Z-matrix)


C H O N S P Cl
6-31+g(d):uff

(LANL2DZ ECP from EMSL=A0 Basis Set Exchange Library)


So any suggestions for modifying the route so that all atoms stay in the de=
fined lavel?

Thanks and Regards

Dear Roby,

You have to define your geometry by using cartesian coordinates, and 
not Z-matrix. For each atom you have to tell Gaussian (if you use 
this program) which layer it belongs to (H or L), and precise that 
you use uff as low layer in the # line. Check out the Gaussian user 
manual for more information.

Hope this helps,

Jean-Christophe Poully

Hello Peter,

I find that this is a common situation with B3LYP and some other DFT
methods.  I find this situtation even when the correct transition state
with large magnitude is found and scf=tight convergence.  In this
situation my solution is to use a small step-size and to "nudge" the
structure in the direction it is not going.  I do the "nudge" by looking
at the difference between the initial and first geometry of the IRC from
the first direction. I then modify the original structure by half this
movement in the opposite direction.

Cheers
 Justin

Hello, everyone,

I try to perform natural transition orbital(NTO) analysis with Gaussian09 according to G09 manual, but always failed.

Here is my route section inptut:
# opt td=(root=1,nstates=6) b3lyp/6-31g(d) density=transition=1 pop(NTO,saveNTO)

 Can anyone kindly tell me how to get NTOs with G09? If it is possible, can you please send me a input sample?

Thank you very much,

Folks,

I have been computing volumes using

CISD/6-311G*  SCF=TIGHT VOLUME=TIGHT

for first and second row atoms with charges of +1, 0, and -1 (and of
course the appropriate multiplicities.)   I find differences between
replicate runs to be as large as 20 percent.  I know that the answers
are supposed to be approximate, but is there any way to tighten this
up, perhaps by putting more points "in the box", or any other means?

Many thanks!

John

Hey every body,
I got the following error when I submit an input file for protien of about =
27000 atoms in order to do AMBER94 calculation using Gaussian 03:

"The maximum of 20000 Z-matrix cards has been exceeded
Error termination via Lnk1e in C:\G03W\l101.exe"

I guess that this error due to exceeding Z-matrix more than 20000 atoms. Is=
 there a keyword=A0 to solve this problem.
Best regards,

MONTREAL, November 19, 2009 =E2=80=93 Chemical Computing Group Inc. (CCG) a=
nnounces the
general release of a graphical interface for Cambridge Crystallographic Data
Centre=E2=80=99s (CCDC=E2=80=99s) GOLD docking software as part of CCG=E2=
=80=99s Molecular Operating
Environment (MOE) software package. The integration technology will be avai=
lable
in the 2009.10 version of MOE.
While the two software programs must be licensed separately, the new interf=
ace
will make running the GOLD docking program from within the MOE software sea=
mless
for end-users.  The interface also allows end-users to conveniently modify =
GOLD
parameters during the simulation.
Paul Labute, President and CEO of CCG said that =E2=80=9CGOLD is an industr=
y leading
protein-ligand docking engine and CCG has worked over the past year to comb=
ine
the strengths of MOE and GOLD.  MOE contains leading preparation and
post-processing functionality while GOLD specifically addresses the docking
problem.  The combination will be of great benefit to CCG and CCDC customers
since MOE=E2=80=99s proton placement, pharmacophore screening, and structur=
e refinement
technology can be combined with GOLD directly.=E2=80=9D
Labute went on to say that =E2=80=9CMany of our customers use MOE as a cent=
ral platform
for their computational pharmaceuticals research and, in recent years, CCG =
has
added components to combine MOE=E2=80=99s strengths with third-party applic=
ations.  We
are very pleased to include GOLD in this capacity and initial customer reac=
tion
to the MOE-GOLD link has been very positive.=E2=80=9D
Chemical Computing Group Inc. (www.chemcomp.com) is a leading supplier of
software solutions for Life Sciences.  CCG=E2=80=99s drug discovery softwar=
e platform is
the Molecular Operating Environment (MOE) that integrates visualization,
simulations and methodology development in one package.  CCG=E2=80=99s info=

Hello Peter,

I encountered a similar problem a couple of times. For me it helped to 
specify a phase: IRC=(...,phase=(...,...),...)

 From the Gaussian Manual regarding the IRC keyword
*Phase*=(/N1 N2/ [/N3/ [/N4/]])
Defines the phase for the transition vector such that "forward" motion 
along the transition vector corresponds to an increase in the specified 
internal coordinate, designated by up to four atom numbers. If two atom 
numbers are given, the coordinate is a bond stretch between the two 
atoms; three atom numbers specify an angle bend, and four atoms define a 
dihedral angle.

Good luck,
Andi

Hello,

I noticed that the following question was asked before here but did not find a 
conclusive answer.

So what can be done if an IRC run in g03 goes in the same direction for both 
the reverse and forward  keywords?

Folks,

I found the answer.. If one has ever tried computing pi to .01
accuracy using a random number generator and the circle inscribed in a
square method, one immediately requires a Huge! number of points..

For volume accuracy for Carbon using 6-311+G*  it was necessary to
raise the number of points in boihrs**3  from the default value of 20
to a value of 40,000...

Cheers!

John

Joe,

I dont know what type of software you are looking for.  Certainly MATLAB has
a PLS TOOLKIT.  Or if you are looking for some older UNIX freeware, Mike Denham of
University of Reading has some software.  Goto:

Dear All,

MolSoft LLC ( www.molsoft.com ) and q.e.d. life science discoveries, 
inc., are conducting a joint two day workshop  on Dec 14-15, 2009 at the 
Molsoft LLC facility in La Jolla, CA USA  entitled "Modern Drug Target 
Crystallography and Structure Based Drug Design".

The course will be taught by two experts in the field: Dr. Bernhard 
Rupp, crystallography textbook author and president of  q.e.d. life 
science discoveries,  and   Dr. Ruben Abagyan, founder of Molsoft LLC 
and Professor of Pharmacology at the University of California San Diego, 
Skaggs School of Pharmacy and Pharmaceutical Sciences.

The provided course materials include a copy of the new and highly 
acclaimed textbook Biomolecular Crystallography: Principles, Practice, 
and Applications to Structural Biology.
