For some reason the selected residues in this image are not displayed as a helix in ChimeraX. I think the command to force it woud be ‘setattr sel res ss_type 1’, but nothing changes (the log says “Assigning ss_type attribute to 2 items”). Same result if I try ‘setattr sel res is_helix 1’. Can anybody please set me straight (and my cartoons helical)?

Using ChimeraX 1.9 for OS X. Thanks for any help.
