About ↑

EPSim is a python program that allows computing the similarity between the Sabatier's ideal reaction energies profile for a given catalytic cycle and the energy profile of potential catalysts. The computed similarities are then locally saved and automatically plotted as a function of a chemically and physically well-defined descriptor.

The code runs on pure python with minimal dependencies:

• numpy
• matplotlib
• pandas

Download and add EPSim.py to your path. No strings attached. Run as:

python epsim.py -i <datafile> -f [feature columns in base 0] -r <reaction energy> -s <number of reaction steps> -d <descriptor file> -c <desc column>

-i Name of the file containing the reaction energies for each catalyst.
-f List of indices corresponding to the columns that contain the reaction energy of each step of the cycle.
-r Reaction energy.
-s Number of steps in the catalystic cycle.
-d File containing the descriptor variable.
-c index of the column containing the descriptor in the descriptor file.
