I have a protein with two doamin connected with two linker. the crystal structure shows only closed conformation. I don't know the open conformation and want to sample it. so I want to only change the conformation of linker region treating the two domain as rigid. is there any protocol available on rosetta that I can use for this purpose? Sorry if I haven't put my question in a very clear way. I am new to rosetta and not well aware of most of the terminology used here.
