Computing interactions in case of atoms' mutations

[Leonard]

I have an app that generates mutations (e.g. some Silicon become Carbon) and I minimize the structrures. However, for efficiency the energy and forces are not recomputed in if the atoms positions do not change, since I have at the begining of UpdateInteractions():

if ((*particleSystem)->getNumberOfChangedPositions() == 0) {
		return;
}

Is there a way to send a signal in case of mutations to reevaluate forces and energies in that case?

Thanks.

In the function, where you generate permutations, you may try to emit

emit(SBStructuralEvent::ParticlePositionChanged);

It seems it works. Thanks.
