RedS software

User registration | Software download

RedS is a user-friendly program for output parsing, atomic coordinate conversion, and vibrational and geometry optimization data manipulation.

With RedS, you can

monitor interatomic distances/angles, S², and the SCF energy during geometry optimizations

monitor changes in internuclear distances (vibrational frequency calculations)

shift the atomic coordinate origin

a parallel shift by a specified (x,y,z)
put (0,0,0) at a specified atom
put (0,0,0) between specified atoms (two or more)

rotate the coordinate system

using Euler angles

rescale or/and format atomic coordinates

exchange X, Y, Z

write atomic coordinates as

a standard XYZ file
a Hyperchem HIN file (HyperCube, Inc.)
a symbolic XYZ matrix for a partial optimization with Gaussian 98/03 (Gaussian, Inc.)

RedS also creates summary reports (those can include multiple items: method of calculation, molecular composition, total energy, frontier orbital energies, HOMO-LUMO gaps, MPA and NPA charges and spin densities of the user-specified atoms, user-specified bond distances and angles, molecular geometry/charge descriptor, etc.) from Gaussian 98/03 output files.

An example of an instruction file (*.DES) for RedS is given below:

# This is an example of a RedS descriptor file. # You can include comment lines in the beginning if the file. # These lines should contain the # character and will be ignored by the program. # GEOMETRY 2 1 28 2 1 2 2 1 4 2 1 6 3 1 28 29 0 WATCH ATOMS 1 2 4 6 28 0 ADD 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 0 IONIC 28 ---- SEARCH ---- up to 10 statements ----- Stoichiometry Output= Error termination ------------------------------------------

These instrictions tell RedS to:

monitor the interactomic distances between atom 1 and atom 28, atom 1 and atom 2, atom 1 and atom 4, atom 1 and atom 6, and the interatomic angle between atoms 1, 28, and 29 (the GEOMETRY keyword);

monitor atomic charges (MPA, NPA and other applicable charge schemes) and spin densities (MPA, NPA) of atoms 1, 2, 4, 6, and 28 (the WATCH ATOMS keyword);

add atomic charges (MPA, NPA and all other applicable charge schemes) and spin densities (MPA, NPA) of atoms 2-27 together and print the corresponding sums (the ADD keyword);

calculate the electrostatic interaction between two fragments of a molecule as a sum q_i * q_j / r_ij (i=1-27 and j=28-to the end of the molecule), where r_ij are interatomic distances and q_i are NPA atomic charges (the IONIC keyword, the first atom of the second fragment (atom 28 in the above example) defines the molecule partitioning into the two fragments) (refer to Inorg. Chem. 2005, 44, pp 4947 - 4960 [PDF] for details);

print all lines which contain user-selected statements such as Error termination and Stoichiometry (the SEARCH keyword).

An example of a summary file (*.SUM) is given below (this summary report has been created using the instruction file shown above on this page):

In the first section of the summary, RedS prints

the name of checkpoint file for this calculation,
the first Gaussian command line (#P)
stoichiometry and basis set information,
total energy and the S² value,
the energies of aplha-spin HOMO and LUMO, and the corresponding energy gap,
(if spin-unrestricted calculation) the energies of beta-spin HOMO and LUMO, and the corresponding energy gap,
the sum q_i * q_j / r_ij for all atom pairs, where r_ij are interatomic distances and q_i are NPA atomic charges.
the sum q_i * q_j / r_ij for all atom pairs, where r_ij are interatomic distances and q_i are electrostatic potential-derived atomic charges.

If RedS is executed with a Gaussian 98/03 optimization output file, RedS prints a summary report (*.SCF) for the optimization:

Here the 1st column indicates the optimization step, the second column is the number of SCF iterations it took to reach the convergence, the 3rd column is the SCF energy, the 4th column is the S² value, and the remaining columns indicate the values of the watched parameters (interatomic distances and angles) as specified by a user in the RedS instruction file.

If RedS is executed with a Gaussian 98/03 frequency output file (the FREQ or OPT=CALCALL keywords in Gaussian), RedS prints a summary report for the calculated normal modes. This report contains normal mode frequencies (cm^-1), IR intensities, and changes in the interatomic distances of user-defined atomic pairs. For example:

Interatomic distance changes for normal modes are reported for atom pairs that are listed in a descriptor file (in the above example, these are: atoms 1 and 18, 1 and 2, 1 and 4, and 1 and 6). This RedS summary allows a user to select and analyze normal modes of interest.

Current program limitations:

The maximum number of atoms: 1000.

The maximum number of atoms in the descriptor file lists (WATCHED ATOMS, watched structural parameters, etc.): 50.
