One option would be molrep molrep -m -mx Of course it assumes that your two structures have overall similar structures and no substantial conformational changes. As the question posed, I think, it does not have solution (only approximations). Almost all programs assume either atom labe

In ccp4i select "Coordinate utilities/Superpose" And then on the first menu select "Superpose using secondary structure matching". It will automatically superpose based on fold rather than atom alignment. (This is the same software as used at the EBI for what used to be called MSDfold). Mi
