If the assembly of interest is not found, you may write in to our mailing list (genome@soe.ucsc.edu) including the NCBI Genbank assembly accession for the requested assembly in the message. These will start with either GCA_ or GCF_. Our agreement with the genomics community is that we wait until the assembly has been deposited into Genbank at NCBI before we process it. See the Assembly Submission Guidelines page at NCBI for directions on their submission process. Also, review the UCSC GenArk Blog posts -for examples of accessing, using reviewing technical details about GenArk hubs.

These are assemblies created and hosted by users and displayed on the Genome Browser. This requires no intervention by the UCSC Genome Browser and can be done for any assembly. See our Quick Start Guide to Assembly Hubs page for additional information and resources. If you create an assembly hub, consider sharing it with others as a Public Hub.
