[chimerax-users] Trouble displaying missing structure dashed lines in cartoon mode

[Jonathan Jih]

Hi Eric,

I can confirm that opening 1www does display pseudobonds properly. I played
around with my pdb files, and it seems if the issue can be resolved if I
either: 1) delete or modify a residue in ChimeraX and then resave the pdb,
or 2) if I fully delete the SEQRES header of each pdb file.

In any case, I'll send you separately two test pdbs I've created. Thanks
for the prompt response!

Jonathan
