# The consequence of including this command is that the bias values that are calculated
# by the METAD action are values for the final simulation bias.
RESTART
Activate restart. More details
# These two commands recompute the CV that was biased in the metadynamics calculation.
The RESTART action with label  calculates somethingcont: 
DISTANCE_FROM_CONTOUR
Calculate the perpendicular distance from a Willard-Chandler dividing surface. More details

POSITIONS
the positions of the atoms that we are calculating the contour from
=2-2400:12,10-2400:12  
ATOM
The atom whose perpendicular distance we are calculating from the contour
=2413  
BANDWIDTH
the bandwidths for kernel density esimtation
=3.0,3.0,3.0  
DIR
the direction perpendicular to the contour that you are looking for
=z  
CONTOUR
the value we would like for the contour

 # This command is used to calculate the final metadynamics bias.  This quantity is
 # required because it used when reweighting each of the trajectory frames.
 The DISTANCE_FROM_CONTOUR action with label cont calculates the following quantities:
