[Chimera-users] Loading .dx maps to chimera

Dear sir, I am trying to load a .dx file (electrostatic potential) onto a molecule in chimera. I successfully loaded the map onto a the molecule's surface. The problem is the potentials I get look differently than the original map. That is, the potentials appear different in the visualization tool of PMV, the program which generated the .dx file I tried to e-load on chimera. Thanks, Maya Schushan, Tel-Aviv university, Israel.
