Iossifov Lab's public GRR-ENCODE is an online collection of curated genomic resources from the ENCODE project, designed for use in GAIn annotation workflows. The repository includes 369 ATAC-seq, 1,401 DNase-seq, 2,943 Histone ChIP-seq, and 3203 TF ChIP-seq experiment-derived resources. By organizing these resources in a consistent, documented format, it helps users discover available annotations, inspect resource summaries and attributes, and use them reproducibly in GAIn workflows. For practical guidance, users can turn to the GAIn documentation for instructions on resource types, selecting or building pipelines, and creating custom GRRs for their own projects.
