The {FFPARAMS} group is employed by the ffoptimize program for input/output specification of FF parameters and their alternation prior FF optimization. The following sections are defined:
[files]
| Key | Default value | Type | Description |
| input | string | name of file with input FF parameters. This files is usually created by other ffoptimize run. | |
| final | 'final.prms' | string | name of file for optimized FF parameters. This file can serve for subsequent FF optimization, which must employ exactly the same order of FF parameters. |
| amber | 'final.frcmod' | logical | name of file for optimized FF parameters in AMBER format |
[control]
| Key | Default value | Type | Description |
| nb_params | string | determine how vdw parameters are handled for assembly of NB type pairs. Supported modes are: normal - standard mode (all reasonable interactions) like-only - only like atoms like-all - all like atoms including a probe all - all interactions The assembly of FF parameters related to NB interactions is also altered by normal/probe mode of individual sets (see probesize in [SET]). | |
| era_only | on | logical | consider only eps, ropt, and alpha parameters |
| lj2exp6_alpha | 12.0 | real | default value of alpha for conversion from ER->ERA |
