Dear Modeller, I try to do a loop modeling using the following script. I got the xxx.BL####0000.pdb and DL#### output files, but the job stop at the step for clustering, the error showed like that:

TOP_________> 1512 686 END_DO

TOP_________> 1513 687 RETURN

TOP_________> 1514 748 CALL ROUTINE = 'cluster', ID1 = 1, ID2 = 20

TOP_________> 1515 606 IF ARGUMENTS CLUSTER_CUT 0, OPERATION = 'LT', THEN = 'SET; CLUSTER_CUT = 1.5'

TOP_________> 1516 607 READ_MODEL FILE = MODEL, ALIGN_CODES = ROOT_NAME

Could you please help me figure out the problem?

Thank you very much!
