Using the build_ah_annots() function, users can turn any resource of class GRanges into an annotation for use in annotatr. The client creates and manages a local cache of files retrieved by the user, helping with quick and reproducible access. The resource includes metadata about each resource, e.g., a textual description, tags, and date of modification. ![]() The AnnotationHub web resource provides a central location where genomic files (e.g., VCF, bed, wig) and other resources from standard locations (e.g., UCSC, Ensembl) can be discovered. ![]() The AnnotationHub Bioconductor package is a client for the AnnotationHub web resource. ![]()
