MOPAC For ChemBio 3D

MagicJigPipe - 6-4-2011 at 20:31

Should this be in the computational section?

I have a perfectly legitimate ;) copy of ChemBio Office Ultra 12.0 but when I attempt to run a MOPAC calculation on a molecule the commands are not there. It just says "Buy online or learn more" under the menu option for MOPAC. Also, the Gaussian interface is nowhere to be found.

Does anyone know how I could get this working (without paying $189+ to buy the full ChemBio Ultra ... again)? My goal is to create a very high quality molecular electrostatic potential map. This is somewhat urgent so any quick help would be greatly appreciated (and so will slow help).

Thanks.

P.S. I can't afford to pay for this because it is purely for academic purposes. Not for pay and not for publication.

EDIT

Also I can't get MacMolPlt to work either. Every time I try to input a file I get an error similar to: "The # of x, y and z coordinates must be on the second line."

Maybe a silly of me, but....have you already installed MOPAC?
If so, you had to install it after ChemBio 3D, in this way the interface is recognized automatically.

Why don't you try with GAMESS? It's free and also is automatically supported by ChemBio.

The ChemBio 3d online manual says that electrostatic potential maps can only be accomplished using MOPAC or Gaussian. I am very new to this so I have no idea why.

I got the MOPAC options to show up but the only ones are "Create input file" and "Parse output file". Since MOPAC costs money that obviously won't work.

MOPAC should be included with ChemBio 3D 12.0 Ultra! WTF is up with that?
