[chimerax-users] How to replace ss_id for a secondary structure region?

Hi, I have a region in my structure (res 208-229) which is displayed as a discontinuous helix when I am certain it is a continuous helix. I want to modify the pdb file to consider it as a continuous helix using chimeraX. I used the following commanlines: settatr #1/K:208-229 res ss_type 1 setattr #1/K:208-229 res ss_id 999 It works. However, I believe the command assigns the same region with a new unique ss_id (999), leaving the original ss_id intact. If I want to replace the the original ss_id with a new sequence range (res 208-229) how would I do that? Also, is there a way to directly text edit pdb file secondary structure list in ChimeraX?
