MoleculeKit

A molecule manipulation library

Getting started

We recommend installing Miniconda on your machine to better manage python packages and environments.

You can install moleculekit either in the "base" conda environment or in a new conda environment. We recommend the second.

Install it into the base conda environment

With conda

(base) user@computer:~$ conda install moleculekit -c acellera

With pip

(base) user@computer:~$ pip install moleculekit

Create a new conda environment

The advantage of conda environments is that you can keep each of your python packages separate with all of their dependencies. This helps avoid conflicts between python packages (i.e. one requires python 2.7 and the other one python 3.6) which might be hard to resolve.

To create a new conda environment named "moleculekit" you run the following command

(base) user@computer:~$ conda create -n moleculekit

Then you activate that conda environment with

(base) user@computer:~$ conda activate moleculekit
(moleculekit) user@computer:~$ 

As you can see the environment changed now. Now you can use the same above install commands to install into the new conda environment.

Optional dependencies of moleculekit

Moleculekit has a small number of optional dependencies which are needed for some of it's functionalities. They were not added to the default dependencies to keep moleculekit a fast and small installation and to avoid unnecessary conflicts with other software. However if you want to leverage all of it's functionality you can install the rest of the dependencies with the following command:

(moleculekit) user@computer:~$ wget https://raw.githubusercontent.com/Acellera/moleculekit/master/extra_requirements.txt
(moleculekit) user@computer:~$ conda install --file extra_requirements.txt -c acellera

Using moleculekit in ipython

Install ipython in the correct conda enviroment using the following command. If you have installed the extra dependencies as above, you can skip this step since it already installs ipython.

(moleculekit) user@computer:~$ conda install ipython

Now you can start an ipython console with

(moleculekit) user@computer:~$ ipython

In the ipython console you can now import any of the modules of moleculekit and use it as normal.

from moleculekit.molecule import Molecule

mol = Molecule('3ptb')
mol.view()
