This will give you illustrative plots of orbitals as well as total electron density. If you are not looking to actually learn these calculations and just need the contour plots, you can use Arguslab. You can use it as an example to generate other Jmol formats. Secondly the hydrophobic tails of the SLS will solvate fatty acids or grease deposits that are attached to the surface of a solid and hold them in suspension, moving them into the liquid bulk phase and thus making it easier to wash them away. In my linux box, the density looks fine in Jmol. Surfactants enable the surface area of contact between the droplet and the substrate to be larger, and thus increase wetting of the substrate 4.
In the recent Pyscf alpha 2 release, a script pyscf/tools/cubegen.py has been added to generate the Gaussian cube file format. The basic functions you probably needed should be very close to the functions used by dft module, such as eval_ao, eval_rho. It should not be too hard to write small script to generate density or other charge surface then plot the surface with Jmol. All of them will use the charges from the PDB file.
#Electrostatic surface jmol software
Then use the resulting file (that should have the charges from the forcefield) and plot the Electrostatic Potential Surface using software like Jmol, MAESTRO, CHIMERA, etc. In pyscf, we are routinely running molden.py to generate molden file and plot the orbital surface with Jmol. Feb 27 at 15:03 You can try to use this PDB as input to run a molecular dynamic job. Most of the tools used to generate the input files can be used for postprocessing too. In addition, there are pyscf and PyQuante, which you mentioned in your question. You can perform your calculations using NWChem, MPQC (both are in the repositories of every recent Linux distribution) or GAMESS-US, which can be downloaded after registration. Input files can be generated using Avogadro, Molden, Gabedit, or wxmacmolplt
#Electrostatic surface jmol free
Actually, some of these free tools are a good choice in any case! Generate an input file with the coordinates of your molecule and commands which calculations to performĪll tools are out there! Unless you have access to the commercially available suites through your institution, I suggest to use those that are free (as in free beer and free speech). You need (some) background knowledge and the tools to Open the scripting window of the applet for command entry. Two suggestions: MolCalc: Calculate Properties > Polarity and Solvation gives you a 3D surface plot with the electrostatic potential superimposed.Īnother suggestion is Avogadro/GAMESS/MacMolPlt. Render a MEP surface in Jmol and use this surface with a PDB in your web page.
