[chimerax-users] Morphing Protein/NA Complex

Hello All, I am trying to create an animation morphing between two states of a protein/nucleic acid complex (one binary, one with an incoming nucleotide). Excluding the nucleotide, the corresponding chain IDs between structures are the same and the sequences are the same. In both ChimeraX and PyMol, I am able to create the morphing animation however, only the protein appears (nucleic acid just does not appear in the animation). Am I missing something obvious? I appreciate any insights. Thanks, Shawn R
