[modeller_usage] Loop Modeling using only part of a PDB file

Dear Modeller Users Residues from PHE 1223 to LEU 1245 are missing from PDB:2RFN. I want to use ONLY the residues from 382 to 406 in my template sequence PDB:3LCK for loop modelling. Remaining part of the residues in the target shouldnot be disturbed.

(2RFN) Target : PHE 1223 to LEU 1245 (24 residues) (3LCK) Template : ASP 382 to TRP 406 (24 residues)

Could you please tell me how to model this?

Regards Robert
