Download | plugins/apbsplugin.py |

Author(s) | Michael G. Lerner |

License | BSD |

This code has been put under version control in the project Pymol-script-repo |

## Software requirements

Register use of the software. This will the authors able to require funding for further development.

Register here, it takes 1 minutes: http://www.poissonboltzmann.org/apbs/downloads

And register here, it takes 1 minutes: http://www.poissonboltzmann.org/pdb2pqr/d/downloads

This plugin is ready "out-of-box" for Linux/Win users through the project Pymol-script-repo

### Windows

Download **APBS.msi** from: http://sourceforge.net/projects/apbs/files/apbs/

### Ubuntu

APBS are in the repository: http://packages.ubuntu.com/search?keywords=apbs

sudo apt-get install apbs

### Compile yourself

If you really want, then see this section: APBS

## Examples

There is a nice tutorial on the APBS homepage: [1]

For further help, there is a mailing list [2] with the corresponding archive [3]

### Example 1

Read about the protein here: http://www.proteopedia.org/wiki/index.php/3ig7

Download: examples/apbsplugin_1.pml | |

This code has been put under version control in the project Pymol-script-repo |

<include src="https://raw.github.com/Pymol-Scripts/Pymol-script-repo/master/examples/apbsplugin_1.pml" highlight="python" />

Open the **APBS Tool2.1...** plugin. The executable should be found for itself:

Click in **Selection to use**, and write **cdk2**.

Click **Set grid**

Click **Run APBS**

To the left in **Molecular Surface**, click **Show**.

Tadaaa!
Hide it again, now show both *Positive* and *Negative* Isosurface

## Troubleshooting

See: APBS#Troubleshooting
