The input trajectory can be in any of the following formats: 

                  ATOMS - atoms used in the calculation of bAIes energy. For more 
                          information on how to specify lists of atoms see \ref Group 

The following arguments are compulsory: 

              DATA_FILE - file with AF2 fit parameters 
                  PRIOR - type of prior to use (NONE, JEFFREYS, CAUCHY 

In addition you may use the following options: 

  NUMERICAL_DERIVATIVES - ( default=off ) calculate the derivatives for these 
                          quantities numerically 
                  NOPBC - ( default=off ) ignore the periodic boundary conditions 
                          when calculating distances 
                   TEMP - temperature in kBt units 
              SIGMA_MIN - minimum value of sigma
