Short helpfile for action CONVERT_TO_FES
****************************************

The following arguments are compulsory: 

                    ARG - the histogram that you would like to convert into a free 
                          energy surface 

In addition you may use the following options: 

              MINTOZERO - ( default=off ) use the conjugate gradient algorithm and 
                          interpolation to find the minimum in the free energy and set the value 
                          found to be the zero of energy. If a minimum in the free energy 
                          cannot be found use the lowest value of the free energy of the 
                          grid as the zero of energy instead 
                   GRID - the histogram that you would like to convert into a free 
                          energy surface (old syntax) 
                   TEMP - the temperature at which you are operating
