[chimerax-users] [chimeraX-users] to display cylinder and helical ribbon of one chain

[Yingyi Zhang]

Dear Elaine,

Great thanks for your confirmation. I thought it might work as you told me
to have another copy and display in separate styles.
However, I tried to select one of the models (pdb) I have, and then
[Present] > Cylinder/Stubs, the display changed for all my opened models.
Did I do something wrong? Or is it due to my version used -  version 0.91
(2019-12-10)?
Many thanks for your help.

Best,
Yingyi
