"model", "optimize" and "refine" are essentially synonyms - they all 
mean "move some atoms in an attempt to reduce the value of the scoring 
function" so what you're asking for doesn't really make sense, unless I 
am not understanding you correctly. Do you perhaps mean that you want to 
model the loops without affecting the rest of the protein? If so, that's 
what the loop modeling protocol does by default; see
