This extension provides the possibility to modify a residue into a different rotamer of the same amino acid type or to mutate it into a residue of a different type.

It also provides a possibility to view all possible rotamers and check clashes.

To use this editor go to Editors toolbar (on the left side of the viewport) > ... > Biology > Rotamers.

The Rotamer editor uses Roland Dunbrack’s Backbone-Dependent Rotamer Library [1].
