[Chimera-users] Surface color by electrostatic potential

Dear all,

I am trying to get some images of the electrostatic potential surface of my
complex. But I have noticed that by using the same .dx file in chimera and
vmd, I am getting different coloring results. Chimera gives more negatively
charged areas. I used the -5 0 5 coloring for both. Is it a difference in
reading the .dx files between the 2 software? I also think that Chimera
colors each side chain by the avg charge. Is it possible to have a more
detailed coloring of the surface according the charges?

Thanks in advance,
