Hi Marco, Hmmm, it may be a bug that this residue does not appear in the Select... Residue menu. However, I can see by looking in the PDB file (or by opening this structure in ChimeraX) that the nonstandard residue name is CH6, so you can disp :CH6 for example, or do other things to it, e.g. color, select, ... select :CH6 The residue does appear in the ChimeraX menu Select... Residue, so the bug seems to be specific to Chimera. I hope this helps, Elaine ----- Elaine C.

Dear all,
When I fetch a protein with a chromophore (PDB code 2h5q), the chromophore, not a standard one, is missing, and not present in the Select-Residue menu. Is there any way to obtain it?
Thanks,
Marco
