AgentBind is a machine-learning framework for analyzing context regions of binding sites and identifying specific non-coding nucleotides with strong effects on binding activities. This code repository contains code for the classification + visualization experiments with the DanQ and DeepSEA architectures respectively.

All experiments are executed on CentOS Linux 7 (core) with Python (v2.7.5). Prior to your code execution, please make sure you have installed the following tools/libraries.
Install FIMO from the MEME-suite
You can download the MEME-suite from http://meme-suite.org/doc/download.html. This will give you a package of tools including FIMO. You also need to run the following command line to set up a short-cut for FIMO:
export PATH={YOUR-PATH}/MEME-Suite/bin:$PATH
Our code requires external python libraries including tensorflow v1.9.0 GPU-version, biopython v1.71, numpy v1.15.4, six v1.14.0, scikit-image v0.14.5, and matplotlib. You can install them with the pip package manager:
pip install numpy six matplotlib biopython sklearn scikit-image tensorflow-gpu==1.9.0
Data for experiments with the DanQ architecture https://drive.google.com/file/d/1dELokJ3D4TSHgGwHomSc5LDLDAwGtZiU/view?usp=sharing
Data for experiments with the DeepSEA architecture https://drive.google.com/file/d/1zj56CnK6VqdJQeFY6JnsReqqEIv8YLgf/view?usp=sharing
AgentBind.py is the go-to python script which execute all the experiments.
Required parameters:
- --datadir: the directory where you stored the downloaded data.
- --motif: a text file containing the names, motifs, and ChIPseq files of TFs of interest. This text file can be found in the given data at
{your-data-path}/table_matrix/table_core_motifs.txt. - --workdir: a directory where to store all the intermediate/oversized files including the well-trained models, one-hot-encoded input sequences, and Grad-CAM annoation scores.
- --resultdir: a directory where to store all the results.
To run AgentBind, you can simply execute:
python AgentBind.py
--motif {your-data-path}/table_matrix/table_core_motifs.txt
--workdir {your-work-path}
--datadir {your-data-path}
--resultdir {your-result-path}
AgentBind reports results of two situations, core motifs present (c) and blocked (b). You can find the correspounding classification results (AUC curves) in: {your-result-path}/{b or c}/{TF-name}+GM12878/. And the Grad-CAM annoation scores are available at {your-work-path}/{TF-name}+GM12878/seqs_one_hot_{b or c}/vis-weights-total/weight.txt.
The python program "AgentBind.py" takes ~24-48 hours to complete. If you need the Grad-CAM annotation scores only, you can directly download them here (DanQ version only):
