[chimerax-users] Specify unmodelled residues

[Elaine Meng]

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#SEQRES>

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
