PENGUINN (Precise Exploration of Nuclear G-quadruplexes Using Interpretable Neural Networks) is a machine learning method based on Convolutional Neural Networks, that learns the characteristics of G4 sequences and predicts probability of forming G4s for given sequences.
Using Git:
git clone https://gitlab.com/RBP_Bioinformatics/penguinn.git
or
git clone git@gitlab.com:RBP_Bioinformatics/penguinn.git
Penguinn is implemented in python using Keras and Tensorflow backend.
Required:
- python, recommended version 3.7
- Keras 2.3.1
- tensorflow 2.3.0
- Biopython
- numpy
Firstly, create a virtual environment.
python -m venv venv
Then, activate it and install the necessary libraries.
source venv/bin/activate
pip install -r requirements.txt
Follow the instructions:
cd path/to/Penguinn/directory
#add rights to execute
chmod +x penguinn.py
#if you've followed the installation steps above and aren't actively sourcing from the previously created virtualenv
source venv/bin/activate
#run the prediction
./penguinn.py --input <input_fasta_file> --output <output_file> --model <path_to_model.h5>
Default model is set to model trained on human dataset with positive:negative samples ratio 1:1, as described in our paper.
