Hi Andreas, Currently the DEN implementation in Phenix can only take one input file, so you'll need to combine all reference chains into one .pdb file. The chain IDs need to match between the working model and the desired reference for each chain in the reference model, which is how the matching is handled. In the future this will be more flexible.

Dear all,

I've started DEN refinement on a structure obtained by MR from data optimistically going to 3.8A. There are several chains of two kinds in the structure. High-resolution structures exist for both. How do I use two reference files for DEN refinement, and how do I assign which chain corresponds to which reference? (Currently, I'm using reference_file = None.)

Thanks.

Andreas
