Thanks Markus, I was going to say exactly the same, at least for those who wanted a short summary.

If anybody wants a little more detail, I recommend scanning through just the top index of the ChimeraX User Guide and seeing if your features of interest are listed: http://www.rbvi.ucsf.edu/chimerax/docs/user/index.html

Of course, you can certainly use both programs. Best, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hello, I'm a first year graduate student and I am wondering what the differences are between Chimera and ChimeraX? I want to use the tools that are present in Chimera, but I don't know if those tools are also present in ChimeraX. Any feedback would be helpful. Best, Bon Ikwuagwu

Hi Francois,

We wrote the ChimeraX solvent excluded surface code a few years ago using a distance grid-based calculation (by default using a grid spacing of 0.5 Angstroms). It is about the same speed as the Chimera surface calculation (MSMS from Michel Sanner) but the appearance is a bit smoother, and it works 100% reliably even on 100,000 or million atom structures. We also added separate code that does an analytic calculation of solvent accessible surface area.

Hello,

In advantages: "Fast and robust solvent-excluded surfaces". What is the algorithm used to compute those?

Regards, F.
