I'm new to rosetta design and looking to do ab initio folding for my first metalloprotein design. I saw the documentation (https://www.rosettacommons.org/docs/latest/application_documentation/structure_prediction/metalloprotein-abrelax), looked at the test inputs, and read the original paper. All of these only address His and Cys as ligands. Is there a way to do other ligands such as Glu or Asp?
Thanks very much for any help!
