Hi Alina, Sorry, Chimera does not calculate surface charge density. Elaine ---------- Elaine C. Meng, Ph.D. UCSF Computer Graphics Lab (Chimera team) and Babbitt Lab Department of Pharmaceutical Chemistry University of California, San Francisco On Mar 1, 2012, at 9:04 AM, IONEL , ALINA ELENA wrote:
Hi, My name is Alina Ionel and I am PhD student. I have a pseudoatomic model (in pdb format) for a capsid protein. I did a representation of the electrostatic potential in Chimera with the option “Coulombic Surface Coloring” for a hexamer, for example. The unit of this potential are in Kcal/mol*e and the surface is colored in a range of values -10 to 10 Kcal/mol*e. I want to know the surface charge density for this hexamer (in C/m2). I need the value. Can you help me, please? Thank you, Alina
