X-PLOR is a program system for computational structural biology. X-PLOR's main focus is the three-dimensional structure determination of macromolecules using crystallographic diffraction or nuclear magnetic resonance (NMR) data. The program is based on an energy function approach: arbitrary combinations of empirical, geometric and effective energy terms describing experimental data may be used. The combined energy function can be minimized by a variety of gradient descent, simulated annealing, and conformational search procedures.
