Hi,

I am looking for an empirical aka. molecular mechanics modelling
program/parameter set that will allow me to model the interaction between
cis-diols present in glycosylated proteins and boronic acid.

Does anybody know which setup will allow us to do this ?

Thanks,

Dear Dave Campano;
     Your best best to obtain the Proloid is to have your friend go to
South America with the prescription.  Asking for a person on this list to
serve as a middleman to "import" the Proloid into the U.S. could put that
person at risk for serious legal consequences -- irregardless of the
humanitarian nature of this request.

     Sorry to tie up the bandwidth with a non-computational chemistry
issue, but I felt that this point needed to be stated.  Thanks.
Sincerely,
Anita Zvaigzne

Subject: Viewmol 2.2 has been released.



What is Viewmol ?
Viewmol is a graphical front end for computational chemistry programs.
It is able to graphically aid in the generation of molecular structures for
computations and to visualize their results. The program's capabilities
include:
- Building and editing of molecules
- Visualization of the geometry of a molecule
- Tracing of a geometry optimization or a MD trajectory
- Animation of normal vibrations or to show them as arrows
- Drawing of IR, Raman, and inelastic neutron scattering spectra
- Drawing of an MO energy level or density of states diagram
- Drawing of basis functions, molecular orbitals, and electron densities
- Display of forces acting on each atom in a certain configuration
- Drawings generated by Viewmol can be saved as TIFF, HPGL, or
  PostScript files
- Animations of normal modes can be converted to a video file (MPEG),
  e. g. for inclusion into World Wide Web documents (requires additional
  programs available on the Internet)
- Interface to the freeware ray tracing program Rayshade (input
  file generation and use of Rayshade from within Viewmol)
- Input and output in a variety of formats, new formats can be added
  easily by the user
At present Viewmol includes input filters for Discover, DMol/DSolid/DMol3,
Gaussian 9x, Gulp, Mopac, and Turbomole outputs as well as for PDB files.
Structures can be saved as MSI car-files, MDL files, and Turbomole
coordinate files. Viewmol's file format has been added to Babel so that
Babel can serve as an input as well as an output filter for coordinates
making all formats Babel can handle accessible by Viewmol.

What is new in version 2.2 ?
- Molecule building and editing capabilities
- More than one molecule can be handled at once
- Automatic file type recognition
- Standard file selection dialog can be used to select files
  to load in addition to the old command line oriented mode
- Periodic systems can be enlarged by adding more unit cells
- Automatic recognition of hydrogen bonds
- Improved drawing of isosurfaces
- Capability to read Mopac outputs
- Gaussian input filter extended to handle Gaussian98 outputs
- Configuration dialog for selecting helper applications and
  language (no need to edit resource files anymore)
- Viewmol file format added to Babel (if anybody knows where
  to submitted patches for Babel, please tell me)
- a lot of bug fixes

What operating systems does Viewmol run on ?
Viewmol was developed using Linux, but it was also ported (or better
recompiled) on a number of other operating systems. Currently, pre-
compiled binaries are available for Linux (dynamically linked with
Lesstif, statically linked with Motif), AIX, and IRIX. The program
should also run on OSF1 and HP-UX, but due to a lack of direct access
to such hardware I couldn't test it.

Where do I get Viewmol ?
Viewmol can be downloaded from the Computational Chemistry List archive
(USA):
- file://ftp.ccl.net/pub/chemistry/software/SOURCES/C/viewmol
or from Akademische Software Kooperation Karlsruhe (Europe):
- file://ftp.ask.uni-karlsruhe.de/pub/education/chemistry
The source code and the precompiled binaries for Linux will also be
available from Sunsite (USA) or your friendly neighbourhood mirror:
- file://sunsite.unc.edu/pub/Linux/apps/graphics/visualization
For the second site it may take a few days before the site
administrators have moved the code to the given location.

The Chemical Information (CINF) Division is planning a series of sessions on
Combinatorial Chemistry Informatics at the fall ACS meeting in New Orleans
(August 1999).  Each session will focus on a different aspect in the
combinatorial chemistry process: from library design, virtual library
analysis, and automated synthesis, through high-throughput screening.  The
four sessions will be presented sequentially to preserve the natural
workflow.

If you  would like submit a talk for one of these sessions please contact
the session organizer at the end of each session description below.


Combinatorial Chemistry Informatics: Library Design
Library design can be the most critical aspect in determining the success or
failure of the resulting combinatorial library.  Selection of the scaffold
and R-groups (reagents) can have a profound effect on how well the library
members bind to the desired target receptor.  Information-based approaches
to the design of combinatorial libraries is resulting in smaller, more
effective libraries.  This session will present novel techniques for library
design and registration.  Please contact Bob Snyder (bobs@mdli.com) for
further information and submission of abstracts.

Combinatorial Chemistry Informatics: Virtual Library Analysis/Diversity
Assessment
This session will focus on the creation and analysis of virtual
combinatorial libraries as a means for pre-screening libraries prior to
their synthesis.  Various diversity measurements will be presented and their
effectiveness measured.  Please contact Bob Snyder (bobs@mdli.com) for
further information and submission of abstracts.

Combinatorial Chemistry Informatics: Automated Synthesis and Validation
This session will cover information management and tracking methods for all
steps of medium or high throughput synthesis.  This includes experimental
set-up, synthesis techniques, purification methods for synthesized
compounds, analytical methods for compound verification, and registration of
validated compounds. Speakers from industry, academia, or government who can
describe approaches to information management for these issues as applied to
their own research programs are preferred.  Please contact Terry Wright
(terryw@mdli.com) for further information and submission of abstracts.

Combinatorial Chemistry Informatics: High-Throughput Screening
Combinatorial libraries pose unique challenges to software programmers and
developers who provide informatics programs for the drug discovery industry.
These challenges include controlling robotic workstations used to create the
libraries as well are register and validate the libraries before they are
run in  High-Throughput Screening (HTS) programs.  This sessions will focus
on how the presenters companies are dealing with this issue.  Please contact
Ron Delmendo (rond@mdli.com) for further information and submission of
abstracts.


Please submit your talks as soon as possible since each session will be
limited to one half day.

Hi there,
is anyone aware of a systematic study exploring the
basis set dependence of NMR chemical shift calculations
(or of other magnetic properties, such as ESR g-tensors)
in the context of DFT? Is there a consensus of what kind
of basis set (size of valence space, polarization, diffuse
functions) is appropriate?
Thanks,
Wolfram

Hi there,

may I can create a GROMACS trajectory file from multiple
series of PDB files which I have got from a MD simulation
with another software (TINKER)?
I want to use the GROMACS software for further analysis
of the MD simulation (e.g. calculation of radius of gyration, RMSD,
H-bond analysis, analysis of secondary structure elements ....).
Thanks

A few weeks ago I posted a question about converting ps file to latex
file, thanks a lot to the people who replied to my question. Here is my
original question:

Based on the replies I recieved, it is not possible to do this job
directly in one step. The practical approach is to extract the
figures/pictures and the text in separate steps - convert ps file
text file, and extract the figures and pictures in it. All the replies are
listed below. Maybe we can scratch a short shell script to do it.

Thank you very much for your replies.

Hi, He Dayong, 

As to my knowledge, there is a program called "ps2ascii" which could
transform a ps file into a text file. But you will lose the image
information. I remember there is a program called "ps2gif" which may
extract images from ps files, but it seems could only extract the first
image. So if the images are in different pages, you can just save them as
one page per ps file, and try to extract those images.

Please let me know if you obtained one; I personally do not think it is
even remotely possible.

Hi Dayong:  

Do you want to convert text files that you have in postscript to latex?
Postscript describes text on a much lower level (i.e., on the level of
single letters or word fragments) than latex and therefore knows nothing
about LaTex's structures like sections, references, environments. I don't
know what size of text you're thinking of, for a short one it is probably
easiest to just type it manually, for large text bodies there might be 
some semi-automated way using OCR software that is also able to guess the
structure from the layout. 

For extracting pictures, try - ps2epsi or pstoepsi: to convert single PS
pages to "encapsulated" PS pictures - xfig: to edit these - psselect: to
select single PS pages from a longer file. 

They are public domain, and you should find them on the web; let me know
if you have questions about that.

Hello Dayong,

as I Know, there is no way to make a conversion, but you can use
\usepackage{epsfig,psfig}
in the header of a latex file and put the diseres postscript in with: 
\psfig{file=postscript_file.ps,width=17cm}
If you've got to make changes in the postscript file, you can use gimp
(www.gimp.org) to do that. 

Good luck

Hi Dayong,

you can incorporate a postscript figure in a number of ways into a latex
document (see book below), but I know of no way to do the Postscript ->
Latex reaction.

Hello Dayong,

I work with latex by many years and I dont know some program that perform
the conversion postscript to latex but I suggest you to ask to the company
PCTEX that sell the latex program, the e-mail is: pti@crl.com and the
phone number is (415) 388.8853

Hi all.

Does anyone know whether there are AM1 parameters for calcium, and
if so, where I can find them?

Thanks
