Method	Details	Software
simulated annealing	INITIAL STRUCTURE CALCULATION WAS CARRIED OUT USING DEFAULT SCRIPT ANNEAL_NORDC.PY AND TEMPERATURE SCHEDULE 3500-TO-25 IN STEPS OF 12.5. REFINEMENT WAS PERFORMED FOR 3000 STRUCTURES USING DEFAULT SCRIPT REFINE_NORDC.PY WITH TEMPERATURE SCHEDULES 1500-TO-25 IN STEPS OF 3.25 AND 500-TO-25 IN STEPS OF 2.25. FOR STRONGER J-COUPLING CONSTRAINTS ANNEALING DURING REFINEMENT ITS SCALING FACTOR IS RAMPED FROM 1 TO 3 DURING COOLING: JCOUP = CREATE_JCOUPPOT("JCOUP","JNA_COUP_SPBC_IN_METHANOL9.TBL", A=6.98,B=-1.38,C=1.72,PHASE=-60.0) RAMPEDPARAMS.APPEND( MULTRAMP(1,3, "JCOUP.SETSCALE( VALUE )") )	NMRPipe
