Subject: Release of RAMVIB: software for modeling molecular vibrations

 Dear Netters,

I am pleased to announce the availability of the RAMVIB software package, free
for academic users. RAMVIB is a set of FORTRAN programs that I wrote some time
ago to ease pains of interpreting resonance Raman spectra of metalloproteins
and metalloporphyrins. It uses normal mode analysis approach to model
vibrations of molecules. RAMVIB can be downloaded from CCL archives:

What makes RAMVIB different from existing NMA software? The partial answer to
this question is listed below:

1) Automatic removal of coordinate redundancies by a new algorithm.
2) A novel method of solving the inverse spectral problem (a.k.a. force field
   refinement) that is convergent even in the case of strong correlation among
   force constants. It delivers high quality fits due to the regularization
   error reduction.
3) It contains an unique set of diagnostic programs for the purpose of testing
   numerical condition of input matrices to eliminate mathematical
   and perform selection of force constants.
4) An input can be constructed for any combination of isotopomers and
   structurally similar molecules as long as they share common subset of
   force constants.
5) It calculates significance matrices of frequencies, isotope shifts and
   potential energy distributions with respect to force constants (as a
   part of the initial process of force constants selection).
6) An automatic force constant selection is performed using a new concept
   of "fitting potential".
7) Automatic sorting and matching of normal modes for different isotopomers.
8) Output of atomic displacement vectors and motion animation files in XYZ
   format readable by XMol to illustrate calculated normal modes.

RAMVIB works under SGI IRIX 5.2 and 6.2 and uses three functions specific

iargc()    - number of command line arguments
getarg()   - returns command line argument in a string variable
etime()    - returns elapsed CPU time

It can be ported to other platforms after these functions are replaced by
appropriate local equivalents.

The paper describing all details of the package has been accepted for
publication in Journal of Molecular Structure and is currently in press.
I will post the exact reference.

Thanks for the interest in my programs.

RAMVIB is a normal mode analysis software that I have written
(1992-1996) in FORTRAN 77 under SGI IRIX 5.2. It has been tested and
proven to work on SGI Indy under IRIX version 5.2 and SGI Indigo^2
under IRIX 6.2. For algorithms, details of operation, etc. see the
following publication:

 Normal Mode Analysis Software for Biological Spectroscopist" J. Mol.
 Struct., 435, 109-121.

Any reports or publications of results obtained with RAMVIB should
acknowledge its use by an appropriate citation.

Please read all the directions below before you proceed any further, and
then follow them carefully.


1) RAMVIB uses Release 1.0 of LAPACK: a library of robust and
 professionally written linear algebra routines in public domain [E.
 Anderson, Z. Bai, C.  Bischof, J.W. Demmel, J.J. Dongarra, J. Du Croz,
 A. Greenbaum, S.  Hammarling, A. McKenney and D. Sorensen, "LAPACK: A
 Portable Linear Algebra Library for High-performance Computers",
 Computer Science Department Technical Report CS-90-105, University of
 Tennessee, Knoxville, 1990]. LAPACK routines are written so that as
 much as possible of the computation is performed by calls to the Basic
 Linear Algebra Subprograms (BLAS) [C.L. Lawson, R.J. Hanson, D. Kincaid
 and F.T. Krogh, "Basic Linear Algebra Subprograms for FORTRAN Usage",
 ACM Trans. Math. Soft., 5 (1979), 308-323].  Both libraries have been
 optimized for Silicon Graphics computers and distributed with the SGI
 FORTRAN compiler (IRIX 5.2 and 6.2 releases).  Before installation make
 sure that you have the library or, usually in the /usr/lib directory. If not,
 you can obtain necessary LAPACK and BLAS routines from NETLIB:

 List of routines is in the header of every source code file.

2) Edit Makefile to modify user editable options (especially
 the installation directory, EXEC_DIR), if necessary.

3) Edit Sizes to adjust array sizes to the available computer memory, if

4) Type "make" to compile, or "make install" and "rehash" to compile and
 install all executables. The environmental variable PATH must contain the
 name of installation directory.

5) Read file_formats.txt.

6) Run examples in directories bh3, cua and nipp. For comparison,
 save original output files. Typing a program name without options,
 e.g. "geom", will display its man page.

The best graphical interface for RAMVIB is program XMol, which is still
distributed from Minnesota Supercomputer Center (version 1.3.1, It can animate normal
modes, display Cartesian displacement vectors and produce output in EPS
format. Several RAMVIB programs write structural output in the XYZ
format readable by XMol.  Unfortunately, the free COFF executable
distributed from MSC will not work under IRIX 6.2. A list of possible
alternatives (not verified) is appended at the end of this file.

Communicate any problems and suggested patches to me,
(Robert Fraczkiewicz), so we can keep the world in sync. If you have a
problem, there's someone else out there who either has had or will have
the same problem. It's usually helpful if you send the list of all your
modifications to the source code.

Happy computing,

RE: Summary of responses to "CCL: IRIX 6.2+ and MSC's XMOL"

>-- Original Question

>-- Executive Summary

 1) Source Code to Xmol is not available (to the best of my knowledge).  It
    was only distributed via executable code.  I (for one) wish one of the
    commerical software vendors would investigate the possibility of
    distributing a working copy of Xmol.  As far as I know, MSC has no plans
    for it beyond what is on their web site now.
    (Hint, Hint, Knudge, Knudge, Wink, Wink - Know what I mean?)

 2) Suggested Replacements
    a) VMD      -
    b) MOLDEN   -
    c) Chime    -
    d) gOpenMol -
