Hi,
I used a derivative of sa.py (attached) to do torsion angle and Cartesian minimization of a spin labeled protein, the minimizations included some NOE and planeDist restraints. The noe energy, noe rms, and planeDist energies were decreased by the minimization but the planeDist rms was increased. How could the planeDist energy decrease and the planeDist rms increase? The minimization script is attached.
