To piggy back on this question of getting more quantitative information out of ChimeraX's electrostatic/coloumbic functions, is there a way to save information about the electrostatic surface as a readable text file (or a .dx file (if that one is human readable))? I was hoping to quantitatively get a delta electrostatic surface of two surfaces at different propka-ph values. Or perhaps a way to generate that difference surface in ChimeraX? ________________________________ From: ChimeraX-users <chimerax-users-bounces@cgl.ucsf.edu> on behalf of Sunisa Yoodee via ChimeraX-users <chimerax-users@cgl.ucsf.edu> Sent: Saturday, February 19, 2022 12:22 AM To: chimerax-users@cgl.ucsf.edu <chimerax-users@cgl.ucsf.edu> Subject: [chimerax-users] Question about Coulombic electrostatic potential Dear UCSF ChimeraX We used the ChimeraX program to calculate electrostatic potential. By using the coulombic command, a molecular surface was generated and colored. However, we also need the electrostatic potential value (kcal/(mol*e))of the protein. Could you please give some advices how to get this value?
