Date: December 21, 2023 at 5:33:38 AM PST To: ChimeraX Users Help Reply-To: Vorländer,Matthias Kopano Hi everyone, I also just struggled with the demands of CIF file deposition to the PDB for a ~50 chain RNA-protein complex and the time it takes to copy-paste sequence into different web interfaces. Would it be possible to interface the ChimeraX sequence association functionalities to write the associated sequence into the mmCIF file? At the end of building large models using many cryo-EM maps the structures often have been cut apart and pieced together many times, so my dream scenario would be to use “alpafold match #model trim false“ to directly write the full-length sequence of the alphafold model into the mmcif file or PDB header for the matches chain. Would be of huge value for PDB deposition! Many thanks and best wishes, Matthias" enhancement closed moderate Sequence duplicate Greg Couch Tom Goddard guillaume.gaullier@… Elaine Meng Tristan Croll all ChimeraX
