STARE is a framework that combines two tasks, which can also work independently:
- score enhancer-gene interactions with the Activity-By-Contact (ABC) model
- derive TF affinities for regions
Those two parts are combined to summarise TF affinities on gene level, which allows for a variety of downstream analyses. If this sounds interesting to you, here's a full documentation on Read the Docs.
STARE and its application are described in our preprint on bioRxiv:

The results of our analyses are available via Zenodo.
The framework is a combination and adaptation which is based on:
