Dear CCL-ers:

      I have limited funds, and thus, I am on a shoestring budget.  I want
to generate 2D chemical structures that can be pasted into Microsoft Word
97 and PowerPoint for publication in a refereed journal and for  
electronic dissemination on the Web.  Also, I have a PDB-type file
generated by using AMBER, and I want to prepare a 3D image that can be
pasted into Microsoft Word 97 as well as PowerPoint for the purpose of
publication.

      Could anyone point me to the best software that would achieve these
goals?  I realize that this is not really a computational chemistry
question, but perhaps some of you have some suggestions anyway.  Thanks.

Respectfully,
Anita I. Zvaigzne

Subject: problem of zwitterion TS search
Content-Type: text/plain; charset=us-ascii
Content-Transfer-Encoding: 7bit

Hi, everyone:
    I have met a problem in TS search. And the deduced TS is a
zwitterion. And are there someone that have the experiences
about solving this kind of problem.
    I have read the manual of mopac, it mentions the COSMO. I set the
NSPA=60,GRADIENTS,1SCF,EPS=78.4,AM1 in the input file, and it seems that
the mopac( from insight97.0) does not accept the keywords of NSPA,EPS.So
I do not know how to use it in MOPAC. Hope you can give me some
suggestion.
   Thanks in advance.


Sincerely,
Mao Xiang

Dear Dr. Zvaigzne,

a very good free 2D structure program is ISIS Draw and for visualization I
would recommend the free program swissPDB in combination with POV Ray (also
free and maybe the best raytracer). This combination produces gorgeous
pictures. Find these programs and many more free and commercial prgrams
listed at

http://www.claessen.net/chemistry/soft_en.html

The idea is simple. Just pre-evaluate the potential on a grid and
use trilinear interpolation. Several docking programs out there use
piecewise
linear approximations to the potential (or forces) on a regular grid:

    Autodock (Goodsell and Olson)
        Proteins: Structure, Function and Genetics 8:195-202 (1990)

    FlexX (Luty, Wasserman, Stouten and Hodge)
         J. Comp. Chem. Vol 16, No 4 454-464 (1995)

   (I'm pretty sure there are several others, but I can't find the refs
    at the moment. The method has also been used in material science 
    simulations)

Also, Oberlin, Trosset and Scheraga have used cubic B-splines on a
regular grid
with great success (Prodock). This method allows for larger grid
elements with
better accuracy, C2 continuity (smooth derivatives) and overall greater
smoothness
which seems to improve the search efficiency:

Oberlin, Scheraga  J. Comp. Chem. Vol 19 No 1 pp 71-85 (1998)
Trosset, Scheraga  J. Comp. Chem. Vol 20 No 4 pp 412-427 (1999)

I've implemented this technique in OrderFour, my own MMFF-based docking
and
simulation code. I'm also experimenting with adaptive and hierarchical
grids
for use in multi-body protein-protein docking. OrderFour will be
generally available
as open-source (I will read-enable the revision control system) as soon
as I can get 
a paper out and get final approval from CTC. We are still making major
revisions to
the API so it's still too early to invite external users to help work on
the code, but 
I'll make a general announcement when things are ready some time this
winter.

Hi,CCLers,

I have read the paper by Peters KP, Fauck J, and
Frommel C mentioned the program APROPOS (JMB,1996)
which can search PDB files for ligand binding sites.
It is said that this program is available for SGI
machines on request from the authors. But I could
not find the email adresses of the authors.

Is there anybody who know the authors and kindly
give me their email addresses?

BEst regards,

Aaron

About two weeks ago, I have submited the following question:

Dear All,

I have a big program which is written in C and Fortran, but mainly in C.
The author compile each module by their own compiler ( cc and f77 on SGI)
and link them by f77.

Now I have another C++ program (still others) and want incorporate it
into the previous big program.

My idea is want to call C++ from C, but compile them separately, and link
them altogether.

Can anyone tell me whether this idea is possible, or have better suggestion?


Now I have received the following replies:

1)
Ernest Friedman-Hill <ejfried@herzberg.ca.sandia.gov>

C can call C++ routines which are declared as extern "C", but no others.

2)
From: hinsen@dirac.cnrs-orleans.fr
This is difficult, and certainly not possible in a portable way.

Mixing C and Fortran is easy, but you should use f77 to link (on
some systems this is not strictly necessary; adding the Fortran
libraries when linking is sufficient).

Mixing C and C++ is also easy, but you must use CC to link.

So for mixing C with C++ and Fortran, you'd have to link with both
CC and f77.

The reason for this problem is that both C++ and Fortran program often
need specific initialization code that is added during linking. An
added complication with C++ is name mangling (the compiler must create
unique names for overloaded functions etc.), but there are ways around
that.

In summary, what you are trying to do is possible only on a system
that allows calling Fortran from C without any special initialization
code for Fortran. I don't know whether this is true for SGI systems.

Hi Konrad,

you are right - as usual :-)

Many times you can resolve the explained problems by incremental linkage
(like ld -r), though.
So you link all your FORTRAN code into one big object file using the
FORTRAN compiler as linker driver, analogous the C++ code using the C++
linker driver. Then you link these into the final exectuable.
The only remaining problem I ever encountered is some trouble about a
duplicate or no main function.

Does anybody knows what is causing this problem and how can I solve that?
It looks like I don't have 
the dxml library. It's possible to get something free to overcome this problem?

Thanks in advance,

Hi again!

On tuesday i posted the following question and got the answers below:

>>

I'm trying to make as accurate calculations as possible on the 
interaction potentials between "atoms in molecules". I wish to make some 
BSSE-correction on some potential scans.

I've tried the following for the colinear F2-F2 interaction:

#RMP2/AUG-cc-pVTZ Scan Massage Test      

F-F F-F  scan r2 

0 1
F1
X1 F1 1.
F2 F1 r1 X1 90.
F3 F1 r2 X1 90. F2 180.
X2 F3 1. F1 90. X1 180.
F4 F3 r1 X2 90. F1 180. 
        Variables:
r2 1.10350222 6 0.1379377775 
r1 1.40120372

3 Nuc 0.0
4 Nuc 0.0

as I want to use the basisfunctions on the second F2-molecule without the 
atoms to get a "maximum" correction for BSSE.

Initially Gaussian seams to read this as taking away the second 
F2-molecule
(output confirms 18 electrons), but when it comes to the scan it is 
confused regarding the numbering of the atoms and takes away not 
the second F2-molecule, but the F3 and X2 in the Z-matrix above.
This results according to output in an odd number of electrons and thus 
a conflict with multiplicity.

Is there a quick way arround this problem, some trivial keyword thing 
that I've missed or is this atom numbering missmatch in Gaussian a 
really unfortunate "feature"?

It could be an unfortunate feature of the scan keyword. I think in this
case, it's worth the effort of getting familiar with the MODREDUNDANT
keyword. It really makes this case trivial.

Here is a reformulation of your input deck. I've converted to cartesian
coordinates, so the redundant internal coordinate code can build a
Z-matrix that doesn't use dummy atoms. Then the atom numbering problem
goes away. :)

#P RMP2/aug-cc-pVTZ opt=modredundant massage  Test      
    
F-F F-F  scan r2
    
0 1 
F  0.0000 0.0000 0.0000
F  0.0000 0.0000 1.40120372
F  0.0000 0.0000 2.50470594
F  0.0000 0.0000 3.90590966

1 2 F
3 4 F
2 3 S 6 0.1379377

3 Nuc 0.0
4 Nuc 0.0

Before that I got a quick and elegant solution to my special case from my 
office room-mate Stefan Andersson:


>>

#RMP2/AUG-cc-pVTZ Scan Massage Test      

F-F F-F  scan r2 

0 1
X1
X2 X1 r2
F1 X2 1. X1 90.
F2 F1 r1 X2 90. X1 180.
F3 X1 1. X2 90. F1 0.
F4 F3 r1 X1 90. X2 180. 
        Variables:
r2 1.10350222 6 0.1379377775 
r1 1.40120372

3 Nuc 0.0
4 Nuc 0.0

<<


In the first case dummy atoms are not used at all, and in the second the 
dummy atoms are simply put at t
he top of the Z-matrix, thereby avoiding the "atom numbering problem" 
with the Scan keyword.

Many thanks both of you!

:-)

The Theoretical Biophysics Group at the University of Illinois is
proud to announce the public release of a new version of NAMD, a
parallel, object-oriented molecular dynamics code designed for
high-performance simulation of large biomolecular systems.  NAMD is
distributed free of charge and includes source code.  NAMD development
is supported by the NIH National Center for Research Resources.

NAMD 2.1b2 is more stable than NAMD 2.0 and adds several new features:

- Mollified impulse multiple timestepping method.

- Faster particle mesh Ewald implementation.

- Periodic boundaries for non-orthogonal cells.

- New interactive molecular dynamics interface to VMD.

NAMD is available from http://www.ks.uiuc.edu/Research/namd/.

The Theoretical Biophysics group encourages NAMD users to be closely
involved in the development process through reporting bugs, contributing
fixes, periodical surveys and via other means.  Any questions or comments
may be directed to namd@ks.uiuc.edu.

We are eager to hear from you, and thank you for using our software!
