# vim:ft=plumedEnables syntax highlighting for PLUMED files in vim. See here for more details. 
UNITSThis command sets the internal units for the code. More details NATURAL use natural units

The UNITS action with label  calculates somethingpThe POSITION action with label p calculates the following quantities:
 Quantity   
 Type   
 Description  
p.x
scalar
the x-component of the atom position
p.y
scalar
the y-component of the atom position
p.z
scalar
the z-component of the atom position: POSITIONCalculate the components of the position of an atom or atoms. More details ATOMthe atom number=1

doubleWellThe CUSTOM action with label doubleWell calculates the following quantities:
 Quantity   
 Type   
 Description  
doubleWell
scalar
an arbitrary function: CUSTOMCalculate a combination of variables using a custom expression. More details ARGthe values input to this function=p.x,p.y PERIODICif the output of your function is periodic then you should specify the periodicity of the function=NO ...
  FUNCthe function you wish to evaluate=2*(x^4+y^4-2*x^2-4*y^2+2*x*y+0.8*x+0.1*y+9.28)
...
potentialThe BIASVALUE action with label potential calculates the following quantities:
 Quantity   
 Type   
 Description  
potential.bias
scalar
the instantaneous value of the bias potential
potential.doubleWell_bias
scalar
one or multiple instances of this quantity can be referenced elsewhere in the input file. these quantities will named with  the arguments of the bias followed by the character string _bias. These quantities tell the user how much the bias is due to each of the colvars. This particular component measures this quantity for the input CV named doubleWell: BIASVALUETakes the value of one variable and use it as a bias More details ARGthe labels of the scalar/vector arguments whose values will be used as a bias on the system=doubleWell

 
metadThe METAD action with label metad calculates the following quantities:
 Quantity   
 Type   
 Description  
metad.bias
scalar
the instantaneous value of the bias potential
metad.rbias
scalar
the instantaneous value of the bias normalized using the c(t) reweighting factor [rbias=bias-rct].This component can be used to obtain a reweighted histogram.
metad.rct
scalar
the reweighting factor c(t).: METADUsed to performed metadynamics on one or more collective variables. This action has hidden defaults. More details ...
  ARGthe labels of the scalars on which the bias will act=p.x
  PACEthe frequency for hill addition=100
  BIASFACTORuse well tempered metadynamics and use this bias factor=20
  HEIGHTthe heights of the Gaussian hills=0.5
  SIGMAthe widths of the Gaussian hills=0.05 
  GRID_MINthe lower bounds for the grid=-3
  GRID_MAXthe upper bounds for the grid=3
  GRID_BINthe number of bins for the grid=300
  CALC_RCT calculate the c(t) reweighting factor and use that to obtain the normalized bias [rbias=bias-rct]
