[chimerax-users] Capping termini ends

[Elaine Meng]

Hi Pranav,
Happy New Year to you too!  You can see our group's holiday card here:
<https://www.rbvi.ucsf.edu/Outreach/card-gallery/2022-us/us.html>

As for your question: You could try displaying the alpha-carbons of the first and last residues in the sphere style.  If you are showing cartoons, you'd also need to use "cartoon suppressBackbone false" to enable showing backbone atoms and cartoons at the same time.

Example:
open 2gbp
cartoon suppress false
show /A:1,309 at ca
style  /A:1,309 at ca sphere

If the spheres aren't the size you want, you can change the VDW radii of those alpha-carbons, e.g. 

size /A:1,309 at ca atomRadius +0.5

I hope this helps,
Elaine
