Hello Bioconductor maintainers

The core team was made aware of an issue with one of the make orgDb functions in AnnotationForge:


Investigating further, NCBI will no longer be updating the gene2unigene file. The url has moved to an ARCHIVE directory and there is an explanation and notice of retirement found here:


We use this function in creating OrgDb's for the AnnotationHub as well as the recommended way for users to make custom OrgDb's from NCBI.

Temporarily we are working on updating the url to the new location but we are thinking of removing the gene2unigene data from the orgDbs. We would like to ask the community especially those that utilize the orgDb objects frequently if this data is still necessary and would the removal of UNIGENE cause a large
disruption to current packages/functions/utilization of objects?

Any feedback is greatly appreciated.

Thank you
