title: Specifying cellular context of transcription factor regulons for exploring context-specific gene regulation programs

description: This repository contains the raw and processed files used in Minaeva et al. 2024.

In this version, we have revised the regulon construction pipeline and expanded the dataset to cover 40 common cell lines.

The code used to generate these files is available at GitHub - LappalainenLab/chip_seq_regulons.

The descriptions of the files contained within each subdirectory are as follows:

1-dataset_stats



per_gene_stats_{approach}_{cell_line}.tsv: Number of TFs regulating a gene according to the respective approach (S2Mb, M2Kb, or S2Kb) in a given cell line.

per_tf_stats_{approach}_{cell_line}.tsv: Number of target genes regulated by a TF according to the respective approach (S2Mb, M2Kb, or S2Kb) in a given cell line.
