| simulated annealing | 50 INITIAL STRUCTURES WERE CALCULATED USING A SIMULATED ANNEALING PROTOCOL WITHIN THE PROGRAM X-PLOR. THESE STRUCTURES WERE THEN ENERGY MINIMIZED USING 1000 CYCLES OF CONJUGATE GRADIENT MINIMIZATION WITH A REFINED FORCEFIELD BASED ON THE PROGRAM CHARMM [BROOKS ET AL. (1983) J. COMPUT. CHEM., 4, 187-217]. | X-PLOR |
