[Chimera-users] Problem with DelPhi in chimera

[Elaine Meng]

We saw your Chimera bug report.  However, the file you attached was not the “.phi” file (electrostatic potential map) output from DelPhi.  It was just the text output from the DelPhi program.  If DelPhi runs successfully on your structure, it will create a separate file, with name ending in .phi, that is the electrostatic potential map.

If by “cube” you mean Gaussian cube grid, Chimera does read that format.

However, this format is handled simply as a map that is not necessarily electrostatic potential, so it would require more steps in Chimera to get the coloring you want.
Best,
Elaine
