ChromBPNet

Bias-factorized, base-resolution convolutional neural network for predicting chromatin accessibility (ATAC-seq / DNase-seq) from DNA sequence.

Disclaimer

This is an UNOFFICIAL implementation of ChromBPNet: bias factorized, base-resolution deep learning models of chromatin accessibility reveal cis-regulatory sequence syntax, transcription factor footprints and regulatory variants by Anusri Pampari, et al.

The OFFICIAL repository of ChromBPNet is at kundajelab/chrombpnet.

The MultiMolecule team has confirmed that the provided model and checkpoints are producing the same intermediate representations as the original implementation.

The team releasing ChromBPNet did not write this model card for this model so this model card has been written by the MultiMolecule team.

Model Details

ChromBPNet is a convolutional neural network (CNN) trained to predict base-resolution chromatin accessibility (ATAC-seq or DNase-seq) from primary DNA sequence with explicit enzyme-bias correction. It builds on the BPNet architecture and internally composes a bias sub-model with an accessibility sub-model. The composed output is factorized into profile and count branches, and the usable base-resolution prediction is reconstructed by ChromBpNetForProfilePrediction.postprocess. Please refer to the Training Details section for more information on the training process.

Model Specification

Input Length	Profile Length	Num Layers	Hidden Size	Bias Hidden Size	Num Parameters (M)	FLOPs (G)	MACs (G)
2114	1000	9 + 5	512	128	6.61	27.83	13.91

The accessibility sub-model has 1 stem convolution + 8 dilated residual blocks (512 filters); the bias sub-model has 1 stem convolution + 4 dilated residual blocks (128 filters). FLOPs and MACs are measured on the canonical 2114 bp ChromBPNet input window.

Usage

The model file depends on the multimolecule library. You can install it using pip:

pip install multimolecule

Direct Use

Chromatin Accessibility Profile Prediction

You can use this model directly to predict base-resolution chromatin accessibility of a DNA sequence:

>>> from multimolecule import DnaTokenizer, ChromBpNetForProfilePrediction

>>> tokenizer = DnaTokenizer.from_pretrained("multimolecule/chrombpnet")
>>> model = ChromBpNetForProfilePrediction.from_pretrained("multimolecule/chrombpnet")
>>> output = model(**tokenizer(("ACGT" * 529)[:2114], return_tensors="pt"))

>>> output.keys()
odict_keys(['profile_logits', 'count_logits'])

>>> output["profile_logits"].shape
torch.Size([1, 1000, 1])

>>> output["count_logits"].shape
torch.Size([1, 1])

>>> track = model.postprocess(output)
>>> track.shape
torch.Size([1, 1000, 1])

The recombined track is the usable, bias-corrected base-resolution accessibility prediction.

Interface

• Input length: 2114 bp DNA window
• Profile length: 1000 bp
• Output: factorized (profile_logits, count_logits); recombine the bias-corrected base-resolution track via ChromBpNetForProfilePrediction.postprocess
• Composition: profile logits added across bias + accessibility sub-models; counts combined via logsumexp

Training Details

ChromBPNet was trained to predict base-resolution chromatin accessibility profiles from ATAC-seq / DNase-seq with explicit enzyme-bias correction.

Training Data

The ChromBPNet model follows the HEK293T GFP-control model from the RoboATAC ChromBPNet Models release (an automated ATAC-seq dataset from the Kundaje/Greenleaf labs). The accessibility and scaled-bias sub-models are combined for bias-corrected prediction.

Training Procedure

Pre-training

The model was trained with a composite loss: a multinomial negative log-likelihood on the per-position profile shape plus a mean-squared-error regression on the log total counts.

• Optimizer: Adam
