Dear developers,

Hello! I recently encountered some problems when using ChimeraX.

When displaying the structure with cartoon, some helix is displayed as loop (Fig A). How to force it to be displayed as helix? I checked the User Guide and used the command "setattr  sel   residues  is_helix   true" for the selected amino acids, but only some amino acids can be displayed as helix (Fig B). Is that need to change ss_ id? I have tried, but it didn't work.

Looking forward to your reply!

Best Regards
