parameter default description use with...
uq 0 Turns on (0)/ off (1) Uncertainty Analysis feature. MESS
uq_n 100 Number of MESS input files generated/number of iterations of MESS calculations MESS
uq_max_runs 5 Maximum number of MESS calculations submitted to the queue at once MESS
well_uq 0.5 Uncertainty in stable intermediate energy, +/- 0.5 kcal/mol MESS
barrier_uq 1.0 Uncertainty in saddle point (TS) energy, +/- 1.0 kcal/mol MESS
freq_uq 1.2 Uncertainty harmonic positive frequencies, factor of 1.2 corresponds to values ranging from 0.833 to 1.2 times the original frequency. Scaling is exact for 100 1/cm, and is larger for smaller and smaller for larger frequencies. Same quantity is used for the hindered rotor uncertainties. MESS
imagfreq_uq 1.1 Uncertainty in imaginary frequency, factor of 1.1 corresponds to values ranging from 0.909 to 1.1 times the original frequency. MESS
epsilon_uq 1.2 Multiplicative uncertainty factor of the epsilon Lennard-Jones parameter. MESS
sigma_uq 1.2 Multiplicative uncertainty factor of the sigma Lennard-Jones parameter. MESS
erelfact_uq 1.2 Multiplicative uncertainty factor of the energy relaxation preexponential factor. MESS
enrelpow_uq 1.2 Multiplicative uncertainty factor of the energy relaxation power. MESS
barrierless_rxn 0 Whether or not you want to include barrierless channels in your MESS input file MESS
barrierless_template '' Name of the barrierless template file, which holds the barrierless block needed for MESS. See the barrierless_mess.tpl file in the tpl directory. MESS
barrierless_prod_template '' Name of the barrierless product template file, which holds the barrierless product block needed for MESS. See the barrierless_prod_mess.tpl file in the tpl directory. MESS
barrierless_energy 0. Energy of the barrierless step of the reaction. MESS
barrierless_states_file '' Name of the barrierless states file, which holds the state information for the barrierless step. See the mc_flux.out file in the tpl directory. MESS

While KinBot is fully restartable, some parameters cannot be changed upon restart without compromising the calculations. These are marked with an asterisk (*).
