REMARK 3 REMARK 3 REFINEMENT. REMARK 3 PROGRAM : CYANA 1.0 REMARK 3 AUTHORS : GUNTERT REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: SOFTWARE USED WAS CYANA AND ITS REMARK 3 INTEGRATED AUTO-ASSIGNMENT MODULE CANDID. THE CHEMICAL SHIFT REMARK 3 IDENTIFICATION TOLERANCE AND TRANSPOSE ERRORS WERE SET TO REMARK 3 0.015 PPM IN BOTH PROTON DIMENSIONS. STARTING WITH DISTANCE REMARK 3 RESTRAINTS DERIVED FROM MANUALLY ASSIGNED NOE CROSS-PEAKS IN REMARK 3 NMRVIEW, A TOTAL NUMBER OF 100 STRUCTURES WERE GENERATED PER REMARK 3 CANDID ROUND WITH 8000 STEPS IN THE CYANA ANNEALING PROTOCOL. REMARK 3 FOR EACH CANDID RUN, TALOS DERIVED ANGLE RESTRAINTS WERE REMARK 3 INCORPORATED (WITH A MINIMUM ERROR SET MANUALLY TO 20 DEGREES) REMARK 3 . THE BEST 20 LOW TARGET FUNCTION VALUE STRUCTURES OF CANDIDS REMARK 3 FINAL ROUND WERE KEPT AS AN ENSEMBLE REPRESENTATION OF THE REMARK 3 FAMILY OF GENERATED STRUCTURES.
