Dear Chimera Users,

I am trying to add missing residues to the protein with the ID: 1u54

But unfortunately for chain A, I cannot do the adding.

I go to "Tools > Structure Editing > Model/Refine Loops". Then I choose "chain A" and I select "all missing structure" and then "apply". But I got an error. Is there any other way for it? for "chain B" it works.

Best Wishes,

Armin
