Hi all I'm trying to get the rotamers for the given residue along the backbone using Dunbrack Backbone Dependent Library. So far, I want to use getRotamers function. But when running this command in the python shell, I got this error "No module named Dunbrack". I don't know if there is a module "Dunbrack" which I should import first. Moreover, besides getRotamers, there are several other functions, e.g. getRotamerParams, extractResInfo, useRotamer, RotamerLibraryInfo, registerLibrary, useBestRotamers, etc and a class called RotamerParams in the same file. I also found there are two associated functions in the Dunbrack folder, say, dependentRotamerParams and independentRotamerParams, which are used in the above functions. Can someone help me distinguish these functions? Which one will be useful if I need a full set of rotamers for certain purpose (i.e. side-chain structure prediction) given the backbone? Thanks in advance. Sorry for disturbing others. Best, Yang
