Hello Matt, The full sequence of what was used in the experiment (crystallography, NMR, ...) comes from the SEQRES records in a PDB file: <https://www.wwpdb.org/documentation/file-format-content/format33/sect3.html#...> Those residues included in the SEQRES but without corresponding atomic coordinates will automatically be shown with the black outline box in the sequence window. If you open a PDB file that doesn't have SEQRES records, the sequence window will only reflect what was read from the coordinates. I hope this helps, Elaine ----- Elaine C.

Hello ChimeraX Team, What information in the PDB file specifies the unmodelled residues (in black box)?:

I’d like to have this information in my own PDB files. Thank you, Matt
