SpaDC
Sequence-based integrative analysis and regulatory inference for spatial chromatin accessibility data
SpaDC: Spatial Chromatin Accessibility Data Analysis
SpaDC is a graph-regularized convolutional neural network for spatial epigenomics. It jointly incorporates DNA sequence, chromatin accessibility, and spatial location to improve the analysis of spatial chromatin accessibility data.
Overview
SpaDC learns sequence-aware representations for denoising and integrating spatial epigenomic datasets. It supports spatial domain identification and regulatory inference, including the discovery of spatial domain-specific cis-regulatory elements and gene regulatory networks.
Key Features
- Sequence-aware modeling: uses DNA sequence together with chromatin accessibility signals
- Spatially informed learning: incorporates spatial-neighbor constraints for robust spatial domain identification
- Integrative analysis: aligns multiple spatial datasets and mitigates batch effects
- Regulatory inference: identifies cis-regulatory elements and infers transcription-factor gene regulatory networks
