Detecting novel human viruses from DNA reads with reverse-complement neural networks.

Project description


DeePaC-strain is a plugin for DeePaC (see below) shipping built-in models for predicting pathogenic potentials of novel strains of known bacterial species.


DeePaC is a python package and a CLI tool for predicting labels (e.g. pathogenic potentials) from short DNA sequences (e.g. Illumina reads) with interpretable reverse-complement neural networks. For details, see our preprint on bioRxiv: and the paper in Bioinformatics: For details regarding the interpretability functionalities of DeePaC, see the preprint here:

Recommended: set up an environment

We recomment setting up an isolated conda environment:

conda create -n my_env python=3.6
conda activate my_env

or, alternatively, a virtualenv:

virtualenv --system-site-packages my_env
source my_env/bin/activate

With conda (recommended)

install with bioconda

You can install DeePaC-strain with bioconda. Set up the bioconda channel first, and then:

conda install deepacstrain

DeePaC will be installed automatically.

With pip

You can also install DeePaC-strain with pip:

pip install deepacstrain

Note: TensorFlow 2.0 is not yet supported.

GPU support

To use GPUs, you need to install the GPU version of TensorFlow. In conda, install tensorflow-gpu from the defaults channel before deepac:

conda remove tensorflow
conda install -c defaults tensorflow-gpu=1.15 
conda install deepacstrain

DeePaC will be installed automatically. Note: TensorFlow 2.0 is not yet supported.

If you're using pip, you need to install CUDA and CuDNN first (see TensorFlow installation guide for details). Then you can do the same as above:

pip uninstall tensorflow
pip install tensorflow-gpu==1.15


DeePaC-strain may be used exactly as the base version of DeePaC. To use the plugin, substitute the deepac command for deepac-strain. Visit for a DeePaC readme describing basic usage.

For example, you can use the following commands:

# See help
deepac-strain --help

# Run quick tests (eg. on CPUs)
deepac-strain test -q
# Full tests on a GPU
deepac-strain test -a -g 1

# Predict using a rapid CNN (trained on VHDB data) using a GPU
deepac-strain predict -r -g 1 input.fasta
# Predict using a sensitive LSTM (trained on VHDB data) using a GPU
deepac-strain predict -s -g 1 input.fasta

Supplementary data and scripts

In the main DeePaC repository ( you can find the R scripts and data files used in the papers for dataset preprocessing and benchmarking.
