Model Overview

The ultimate use of this model is to denoise ATAC-seq data and create a higher-quality signal for a much cheaper cost compared to collecting high quality data.

Model Architecture

The model is a residual neural network consisting of 5 residual blocks that produce the denoised ATAC-seq signal, followed by 2 additional residual blocks and a sigmoid layer to produce classification (peak calling) output. All residual blocks are composed of 1-dimensional convolutional layers and ReLU activations.


This model was trained on bulk ATAC-seq data from 4 blood cell types (B cells, NK cells, CD4+ and CD8+ T cells). Noisy data depth is 0.2 million reads. Clean data depth is 50 million reads. Data was obtained from Corces, M. R. et al. Lineage-specific and single-cell chromatin accessibility charts human hematopoiesis and leukemia evolution. Nature Genetics vol. 48 1193–1203 (2016).

Pretrained Models: The best performing model can be found under the File Broswer tab, models directory.

Configs: AtacWorks has the ability to take in config files that specify various command line options. This makes it easy to share the exact parameters the model was trained with. You can find the configs for this model under the File Browser tab, configs folder.


The input data for this model consists of noisy ATAC-seq coverage tracks. The labels to train the model are clean ATAC-seq coverage tracks and peak calls based on the clean coverage tracks.


This model learned to denoise a 0.2 Million read depth ATAC-seq signal to resemble a 50 Miliion read depth signal, and to call peaks from the noisy ATAC-seq signal. The output from AtacWorks is two bedGraph, optionally bigWig files, one containing a denoised coverage track and other containing denoised peaks.

Output Files: For the convenience of users, we have uploaded the output files generated by AtacWorks. They can be found under File Browser tab, output directory.
