I m seeing an error when I attempt to implement RadiusOfGyrationSq
# Add custom CV for radius of gyration
num_atoms = system.getNumParticles()
print(f Number of atoms in system: {num_atoms} )

Hi,
So I use the following code to define Rg
# set umbrella bias
n_atoms = top.getNumAtoms()
rg = cvpack.RadiusOfGyration(list(range(n_atoms)), pbc=protein.use_pbc, weighByMass=True)
rg_bias = mm.CustomCVForce(f ...
