I made models of 2 domains present in my protein using I-TASSER. I now need a model that contains both domains as well as the unstructured loop connecting them. I know I-TASSER is not optimized for this. What is the best method moving forward to create a multi-domain model? Should I use AIDA to improve model afterwards? Is there something else I should use that would be better? Please note that I have a Mac and no knowledge of command line so my options are very limited.
