I would like to model a protein using two templates and (!) define which parts of the structure are modeled by which template. I.e. the core of the structure by template_1 and a specific loop by template_2. The template structures are already aligned. Any suggestions and comments will be highly appreciated. I am aware that I could generate a "Fused_template_structure" manually but it would be really nice if I could do it in an automatic fashion. 

Kind regards,

Simone
