I am evaluating the speed of a simple Coulombic calculation vs. Poisson-Boltzmann for interactive use.  If the PB calculation always takes many minutes for reasonable results then I would probably make the Coulombic calculation available "directly" (i.e. the results made available in that same session as a volume data set or a surface coloring) but allow the PB input (i.e. a PQR file for APBS) to be easily created.  Adding these features has become feasible now that Chimera includes charge-assignment capabilities.   I'm open to opinions/suggestions about what people would like to see in this regard.

  It may be simple to make DelphiController work on Windows since the

only obvious problem I saw was in the command used to invoke Delphi.

That seems like a simple step to try before we include some other

electrostatics calculation.  Eric Pettersen is the one who is looking

at electrostatics and maybe he can comment further.


Conrad is investigating getting Delphi to work on Windows and will be following up.
