Dear all,
I want to use ABF to calculate PMF,so I am running simulation with
colvars. However, the NAMD2.8 said :

TCL: Setting parameter colvars to on
FATAL ERROR: Setting parameter colvars from script failed!

FATAL ERROR: Setting parameter colvars from script failed!

FATAL ERROR: Setting parameter colvars from script failed!

FATAL ERROR: Setting parameter colvars from script failed!

FATAL ERROR: Setting parameter colvars from script failed!

my colvars flie :
colvarsTrajFrequency 100
colvarsRestartFrequency 1000

colvar {
    name IonDistance

    width 0.1

    lowerboundary -45.6
    upperboundary 45.6

    lowerWallConstant 10.0
    upperWallConstant 10.0

    distanceZ {
          main {
             atomsFile ./main_atom.pdb
             atomsCol B
             atomsColValue 1.0
          }
          ref {
          atomsFile ./ref_atom_2.pdb
          atomsCol O
          atomsColValue 1.0
          }
    }
}

abf {
    colvars IonDistance
    fullSamples 100
    hideJacobian
}

I want to know which parameter has problem?
Thanks!

P.S.
There are tclForces parameters in my conf flie.
