biobb_workflows

Binder bioexcel/biobb_workflows Apache License, 2.0

The Jupyter notebook Lysozyme.ipynb shows a Lysozyme + Mutations tutorial using the BioExcel building blocks biobb.

You may execute the notebook on a free cloud instance using myBinder, or for better performance/extensibility in your on instance of Jupyter Notebook.

Docker image

The Docker image bioexcel/biobb_workflows is provided, based on myBinder.

Launch it as:

docker run -p 8888:8888 -it bioexcel/biobb_workflows

Then access the Notebook at http://127.0.0.1:8888/ using the provided token.

Tip: If you have an NVIDIA GPU and NVIDIA Docker installed, launch with nvidia-docker instead of docker for hardware-accelerated GROMACS.

BioConda installation

For your own installation it is recommended to use BioConda on Linux or OS X. See the BioConda installation instructions for details. In brief:

First, install MiniConda (Python 3.x recommended). Then activate BioConda channels:

conda config --add channels defaults
conda config --add channels bioconda
conda config --add channels conda-forge

Make a new Conda environment to keep our dependencies:

conda create -n biobb biobb_md biobb_io biobb_model nglview=1.2.0 simpletraj gromacs

Tip: Remove gromacs above if you have already installed GROMACS that you compiled with hardware accelerations like NVidia CUDA.

Activate the Conda environment:

conda activate biobb

OpenCL implementations

After activating the Conda environment for the first time you may see a warning equivalent to:

WARNING: No ICDs were found. Either,
- Install a conda package providing a OpenCL implementation (pocl, oclgrind) or 
- Make your system-wide implementation visible by doing 'ln -s /etc/OpenCL/vendors /home/USER/miniconda3/envs/biobb/etc/OpenCL/vendors'  

The PyOpenCl documentation suggests how to proceed. OS X users should use conda install khronos-opencl-icd-loader which can use GPU hardware installed, while in Linux you can either provide a software-based OpenCL implementation with conda install pocl or (recommended) use GPU-specific hardware implementation found in /etc/OpenCL/vendors (e.g. apt install nvidia-driver-390) by creating the symlink as suggested.

Start Jupyter Notebook

Activate the nglview extension and start Jupyter Notebook:

jupyter-nbextension enable nglview --py --sys-prefix
jupyter notebook biobb_workflows/lysozyme_tutorial/notebooks/Lysozyme.ipynb
