Bob and Martin, I've asked Bob before about Jmol and Chime and the apparent ability of Chime to calculate MEP surfaces. He's consistently and fairly argued that this is not something Jmol should encompass. This disappointed me because I use Chime MEP surfaces for teaching basic ideas about molecular polarity, but it's not a lightly-taken decision.
I've converted my old Chime resources into Jmol ones now, except the ones using MEP surfaces (and the dreaded Sculpt mode). Wanting to push on with my Chime --> Jmol conversions, I have a newbie question for Bob: What software would you use to calculate the MEP surface properly from a mol (or other) file? Ewen PS Sorry if I missed it Bob, but did anything happen with lipophilic potential colouring of surfaces? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Hanson Sent: 02 May 2007 17:02 To: [email protected] Subject: Re: [Jmol-users] Requesting electrostatic potential with Rasmol coloring scheme for MOL and CML files Martin Slavík wrote: >In Jmol I really miss displaying electrostatic potential with /Rasmol/ >coloring scheme (it is usefull for depicting small variances in partial >charges and handy for educational purposes) for every file type. > I'm not certain what that coloring scheme is, but it's possible that you aren't taking full advantage of the isosurface command. You can set the range of colors to whatever you want, and there are five or six color schemes.

So we made the decision this past summer to not have Jmol do that and instead allow for any file type that has charge data in it already to be displayed. It's a slightly different philosophy. But there are many file types now that are supported, and if you have another, I can do that in a day. > In addition, for files without appropriate data >(MOL, CML), label %P displays partial charge=0 instead of -- or some >approximation (as in Accelrys ViewerLite). > > > Again, Jmol is not going to get into the approximation business in this regard. I think as a web page developer you just have to know what files you are working with and choose file types that are appropriate. Then you won't have this problem. >I will enjoy to have possibility to display such rough approximation >(electrostatic potential with /Rasmol/ coloring scheme) and/or label for >partial charge for files without appropriate data. > > Not going to happen, sorry. That decision is final - we need the appropriate data. Partially this is so that we can say that when you look at a rendering of MEP in Jmol it reflects what the calculation intended, not some crude approximation invented by me. That's one difference between Jmol and Chime. Is there a reason you can't have control over using the %P label option only when appropriate?
