shift_coords.py

• creates shifted xyz files and save them in shifted_files
• writes Qchem input files to get SCF energy (1st derivatives) and save Q-Chem input files for force calculation in a directory called get_forces_qchem_input_files
• to compile: python shift_coords.py [options] [xyzfile]

Run all input files on Q-Chem at the same time and move all output files under one directory

get_freq.py

• reads in all output files, find the SCF energy and write new grad files
• copies all grad files and re-write name the files accordingly
• saves all frequencies in a csv file under a directory called [rootname]_freq_compare
• saves all enthalpy and entropy in another csv file under a directory called [rootname]_freq_compare
• to compile: python get_freq.py [option] [qchem force calculation output files dir] [xyzfile]

Use parse_enthalpy_entropy.py to parse values of enthalpy and entropy from output file for comparison purpose, it can be found at python_qinput/luna Make sure that the Q-Chem's output file of frequency job is in [rootname]_freq_compare

• to compile: python parse_enthalpy_entropy.py [rootname]_freq_compare

compare_results.py

• compares frequencies generated from this program versus from Q-Chem and returns a frequency_RMSE.csv file
• compares enthalpy and entropy generated from this program versus from Q-Chem and returns a enthalpy_entropy_RMSE.csv file
• to compile: python compare_results.py [rootname]_freq_compare
