Installation

It is strongly recommended a separate environment for this package, either with conda or venv. After activating the environment, simply run:

.. code-block:: bash

pip install git+https://github.com/tiwarylab/af2rave.git

This should take ~5 min depending on internet and computer. If you want the folding module installed, too. You need to install ColabFold separately. One way to do it is with conda and download its parameters.

.. code-block:: bash

conda install colabfold
python -m colabfold.download

Demo

A demonstration is available in the notebook folder. To run it in Google Colab, simply open the notebook, and replace github.com with githubtocolab.com. You can generate your own structures with Colab, or upload the structures of DDR1 we generated in datasets/DDR1 to the notebook. The notebook should give cluster centers in ~2 mins without structure generation or ~40 mins with AlphaFold2 part.
