Method Detail

setComment

public void setComment(java.lang.String str)

evaluateAtoms

public void evaluateAtoms()

Description copied from class: AbstractEnergy

Evaluates the energy term and devides the energy between the atoms. The energy field of each atom is assigned a value - its contribution to the total energy sum.

Specified by:

evaluateAtoms in class AbstractEnergy

evaluate

public double evaluate()

Description copied from class: AbstractEnergy

Evaluates the energy term and update the derivatives.

Specified by:

evaluate in class AbstractEnergy

evaluate

public final double evaluate(boolean updateAtoms)

updateSigmVals

private final void updateSigmVals(Distance dis)

Here goes the processing of the various sigmoid functions concerning atom1 and atom2 in the Distance - dis. The results are updated in the fields of the CAsolvateDistanceAttribute of dis - sigmaValues.

calcMeansAndStd

private void calcMeansAndStd(double[][] pp)
