I just realized that you could do it even without using truncate_to_polyala:

phenix.pdbtools model.pdb keep="backbone"

or, equivalently:

phenix.pdbtools model.pdb remove="sidechain"

and it works for both: proteins and RNA/DNA.

Though the original question was for protein, is there a mutate to  
poly C for RNA as well? :)

It just came to mind right now.

Hi,

the next nightly build of PHENIX will have this option available from
phenix.pdbtools.

Example:

phenix.pdbtools model.pdb truncate_to_polyala=true

As always, any feedback will be very appreciated.

Pavel.

Is there an option or a phenix.* utility to mutate a MR model to poly
ALA before the MR is done?
