How do I refine a specific region of my protein model so that it perfectly superposes with a template peptide PDB with the same sequence?

I have a protein model and want to replace a 12-amino acids-long region within the center of the model with those of a PDB file containing a 12-amino acids long peptide of the same sequence. This...
