[Chimera-users] calculating electrostatic potential

[Elaine Meng]

Dr. Prabuddha Bhattacharya,

The Chimera tutorials are here:
<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/frametut.html>

... and there is one specifically including coloring by electrostatic potential.  See the second section of the tutorial: "Coulombic electrostatic potential" for the easier approach if you just want surface coloring.

<https://www.rbvi.ucsf.edu/chimera/current/docs/UsersGuide/tutorials/surfprop.html#esp1>

However, if you want to calculate a map of the Poisson-Boltzmann electrostatic potential, there is no way to do that directly in Chimera currently.  Instead you will need to use some other program or web server, such as the APBS or DelPhi web servers, links provided in the third part of the tutorial:

I hope this helps,
Elaine
