Iossifov Lab's public GRR is an online collection of curated genomic resources designed for use in GAIn annotation workflows. The repository includes reference genomes, gene models, genomic scores, CNV collections, gene properties, gene sets, and annotation pipelines. 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.
