Description of the software

AutoMeKin (formerly known as tsscds) is a computer program that has been designed to discover reaction mechanisms and solve the kinetics in an automated fashion. AutoMeKin obtains transition state guess structures from trajectory simulations of the highly vibrationally excited species. From the obtained TS structures, minima and product fragments are determined following the intrinsic reaction coordinate. Finally, having determined the stationary points, the reaction network is constructed and the kinetics is solved. The program is interfaced with MOPAC2016 and Gaussian 09 (G09).

Details of the method are described in these two publications: 1 2

Users are encouraged to read the tutorial , which is thought to guide you through the various steps necessary to predict reaction mechanisms and kinetics of unimolecular decompositions. To facilitate the presentation, we consider, as an example, the decomposition of formic acid (FA).

The program has been tested on the following Linux distros: CentOS 7, Red Hat Enterprise Linux and Ubuntu 16.04.3 LTS

Downloads

Download the source code and the tutorial

Install the code

To install the code read the Installation instructions

Program execution

To start using any of the scripts of the program, you have to load tsscds/2018 module:

module load tsscds/2018

To run the low-level calculations use:

nohup llcalcs.sh molecule.dat ntasks niter runningtasks >llcalcs.log 2>&1 &

where:
molecule is the name of your molecule
ntasks is the number of tasks
niter is the number of iterations
runningtasks is the number of simultaneous tasks

To run the high-level calculations use:

nohup hlcalcs.sh molecule.dat runningtasks >hlcalcs.log 2>&1 &

For more details, follow the instructions given in the tutorial
