Demo

Try running our demos on Google Colab:

  • Dynamic Use-Case (with a custom MD trajectory as input)
    • Dynamic Use-Case
    • This demo features an MD test example of a small pentapeptide
    • You can also upload your own trajectory!
  • Static Use-Case (with UniProt ID as input)
    • Static Use-Case
    • This demo features the P03372 UniProt accession related to the ER-alpha estrogent receptor
    • But you can try it out with your own choice of UniProt ID too!

Try runnning our notebooks on Binder: Binder

Installation instructions

Docker image pull

The prefered and easiest is by pulling the docker image made available publicly.

prerequisites: docker

Just pull the image:

docker pull ac121/engens:latest

You're all set!

Note: this step should not take longer than 15min. On Windows the PowerShell sometimes gets stuck - do a right click in the terminal to check the progress after 10-15min.

For other installation options check the section Advanced Installation bellow.

Running EnGens

Linux: run the following command from the working directory with this code

docker run -it --rm -v $(pwd):/home/engen/ -p 8888:8888 ac121/engens:latest jupyter notebook --ip=0.0.0.0 --port=8888

Windows: run the following command from the working directory with this code

docker run -it --rm -v ${pwd}:/home/engen/ -p 8888:8888 ac121/engens:latest jupyter notebook --ip=0.0.0.0 --port=8888

Using these commands a link will pop up (something like http://127.0.0.1:8888/?token=7f4fb1ded621bda931880bd3cd1c62431d47abfbb91116ac). Follow this link and you will find a set of notebooks:

  • Workflow1-crystal_structures.ipynb
  • Workflow1-FeatureExtraction.ipynb
  • Workflow2-DimensionalityReduction.ipynb
  • Workflow3-Clustering.ipynb
  • Workflow4-ResultSummary.ipynb

For static workflow start with Workflow1-crystal_structures.ipynb and continue with Workflow2-4. For dynamic workflow start with Workflow1-FeatureExtraction.ipynb and continue with Workflow2-4.


Code

All the code and classes used in the notebooks are found in the directory ./EnGeNs/engens_code/engens/core/

Advanced Installation

1. Docker image build

You can clone this repo and build the docker image yourself.

prerequisites: git, docker

  1. Clone the github repo:
git clone https://github.com/KavrakiLab/EnGens.git
  1. Build the image:
cd EnGens
docker build -t test_engens:latest .

You're all set!

2. Conda environment build

If you don't want to use docker, you can clone this repo and install using conda (or mamba which will be faster).

prerequisites: conda or mamba

  1. Clone the github repo:
git clone https://github.com/KavrakiLab/EnGens.git
  1. Install with conda (or mamba)
cd EnGens
conda env create -f ./environment.yaml
#mamba env create -f ./environment.yml

conda activate engens
#mamba activate engens

./linux_setup.sh
#or ./windows_setup.sh

If the command ./linux_setup.sh fails due to not having pypatch - do pip install pypatch.
