Sorry, I have just found the description for sides  N

Subject: how to change the radius of loop

 

Hello,

 

Does anyone know how to modify the radius of loops?

I am trying to show structural difference between the three aligned proteins
with the cartoon helices shown as tubes.

However, when I reduced the helix radius from 2 to 1 (

"cartoon style modeh tube rad 1 sides 24"), the radius of a helix is only
about twice that of a loop/coil.

 

Also, what does the number "24" do in the "sides 24"?. I could not find the
description on this on ChimeraX

 

Any help will be appreciated.

Thanks,

 

Best wishes,

Winston
