LABELa label for the action so that its output can be referenced in the input to other actions=rc  ARGthe values input to this function=s1,s2,ma1,ma2 COEFFICIENTS the coefficients of the arguments in your function=0.513,0.938,-0.129,1.00 PERIODICif the output of your function is periodic then you should specify the periodicity of the function=NO
... COMBINE

METADUsed to performed metadynamics on one or more collective variables. More details ...

 ARGthe labels of the scalars on which the bias will act=rc   # Label of the CV
 PACEthe frequency for hill addition=2500   # Pace in the deposition of the gaussians
 HEIGHTthe heights of the Gaussian hills=18.705   # Height of the gaussians in energy units kJ/mol. This is 5 kT.
 SIGMAthe widths of the Gaussian hills=0.10   # Width of the gaussian in CV units
 FILE a file in which the list of added hills is stored=HILLS   # File where the information of the gaussians is printed
 BIASFACTORuse well tempered metadynamics and use this bias factor=50.0   # Bias factor in well tempered simulations
 TEMPthe system temperature - this is only needed if you are doing well-tempered metadynamics=450.0   # Temperature in Kelvin. Only needed for well tempered simulations
 GRID_MINthe lower bounds for the grid=-20.0   # The following three lines define a grid for the calculation of the bias potential. Use it **always**.
 GRID_MAXthe upper bounds for the grid=2.0
 GRID_BINthe number of bins for the grid=600
 CALC_RCT calculate the c(t) reweighting factor and use that to obtain the normalized bias [rbias=bias-rct]
