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. |

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