Betreff: Re: [chimerax-users] Ca trace

Hi Valeria,

If you mean straight lines between CA atoms, sorry no, there is no CA trace display in ChimeraX yet. It is #694 in our ticket database.

You can show a spaghetti-type ribbon that goes through the exact CA positions but is curved in between, e.g.

cartoon

cartoon style arrows f xsect oval width 1 thick 1

as shown for the purple protein in rightmost image here:

In that case you could use different width and thickness values. If you want to additionally show CA balls, maybe something like:

cartoon suppressBackbone false

cartoon style arrows f xsect oval width .5 thick .5

show @ca

style @ca ball

… as shown in attached image. I hope this helps,

Elaine

Dear all,
I was wondering, is there an option to just show a Ca trace in ChimeraX?
If yes, can one modify the width of it?
Thanks a lot in advance,
Valeria
