COMMITTOR
This is part of the analysis module

Does a committor analysis.

ARG the input for this action is the scalar output from one or more other actions. The particular scalars that you will use are referenced using the label of the action. If the label appears on its own then it is assumed that the Action calculates a single scalar value. The value of this scalar is thus used as the input to this new action. If * or *.* appears the scalars calculated by all the proceding actions in the input file are taken. Some actions have multi-component outputs and each component of the output has a specific label. For example a DISTANCE action labelled dist may have three componets x, y and z. To take just the x component you should use dist.x, if you wish to take all three components then use dist.*.More information on the referencing of Actions can be found in the section of the manual on the PLUMED Getting started. Scalar values can also be referenced using POSIX regular expressions as detailed in the section on Regular Expressions. To use this feature you you must compile PLUMED with the appropriate flag.
STRIDE ( default=1 ) the frequency with which the CVs are analysed
BASIN_A_LOWER the lower bounds of Basin A
BASIN_A_UPPER the upper bounds of Basin A
BASIN_B_LOWER the lower bounds of Basin B
BASIN_B_UPPER the upper bounds of Basin B
FILE the name of the file on which to output these quantities
FMT

the format that should be used to output real numbers

Examples
The following input monitors two torsional angles during a simulation, defines two basins (A and B) as a function of the two torsions and stops the simulation when it falls in one of the two. In the log file will be shown the latest values for the CVs and the basin reached.
