Each collective variable used in an ABF simulation is defined in a separate section [CV]. These sections are included either in a special group (if the collective variables are defined directly in the main control file), or in the {MAIN} group of a separate file. The group name or file name is determined by the `fabfdef` option specified in the [file] section.

[CV]

Key Default value Type Description

min_value real Minimum value used for discretizing the collective variable.
max_value real Maximum value used for discretizing the collective variable.
nbins integer Number of bins used for discretizing the collective variable.
wfac 0 real Width factor for Gaussian kernel smoothing, given as a multiplier of the bin width.
