Introduction
AutoMeKin (formerly tsscds) has been designed to discover reaction mechanisms in an automated fashion. Transition states are located using MD simulations and Graph Theory algorithms. Monte Carlo simulations afford kinetic results. The only input is a starting structure in XYZ format. The method is described in these two publications: 1 2. At present MOPAC2016, Entos Qcore and Gaussian (G09/G16) are interfaced with AutoMeKin. The program has been tested on the following Linux distros: CentOS 7, Red Hat Enterprise Linux and Ubuntu 20.04 LTS.
To give you a flavor of the capabilities of the program you can try our web interface or Google Colab

Program execution
Unless you donwloaded the singularity container (in that case skip this step), to start using any of the scripts of the program, load the amk/2021 module:
module load amk/2021
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

News
AutoMeKin is now interfaced with Gaussian 16 (from rev. 1131)
The Python library amk-tools can be employed to read, process and visualize reaction networks generated by AutoMeKin and is available in the latest singularity container (and through our web interface). Here is the paper describing the new tool: Garay-Ruiz et al. ACS Phys. Chem. Au 2022
AutoMekin got the GEQC-RSEQ 2021 Methodology Development Prize.
AutoMeKin now includes barrierless channels. However, these channels are not considered in the kinetics.
AutoMeKin has been interfaced with Entos Qcore.
AutoMeKin has been interfaced with BXDE to enhance its efficiency ( R. A. Jara-Toro et al. ChemSystemsChem doi: 10.1002/syst.201900024).
The method has also been recently generalized in a collaboration with Dani Pelaez and co-workers to study van der Waals structures ( S. Kopec et al. Int. J. Quantum Chem. 2019, 119, e26008 ) and also to generate sum-of-products PESs for quantum dynamics ( R. Panades-Barrueta et al. Frontiers in Chemistry 2019, 7, 576).
