Hi Josh
Sorry I send everyone wrong script. this is the once which is
showing the error "colvars: Error: keyword "refpositionsfile" is not
supported, or not recognized in this context."
olvar {
name spin
outputAppliedForce on
spinAngle {
atoms {
atomsFile spin.pdb
atomsCol B
atomsColValue 1
refPositionsFile spin.pdb
refPositionsCol B
refPositionsColValue 1
axis (-0.47851067781448364,
0.23966480791568756, 0.8447416424751282)
}
atoms {
psfSegID AP1
atomNameResidueRange CA 212-220
centerReference yes
rotateReference yes
fittingGroup {
psfSegID AP1
atomNameResidueRange CA 1-211
}
refPositionsFile spin.pdb
}
}
}
harmonic {
name harm
colvars spin
forceConstant 16200 # kcal/mol/deg^2
centers 0
targetCenters -90
targetNumSteps 10000000
}
Thanks
Dhiraj
