We're getting a facelift in the near future!

August 28, 2014

The updates will provide a more organized approach to searching the data and going through results - especially important given the recent release of new genomes. Don't worry: all of the legacy genomes (CHO-K1 GenBank, and earlier CHO-K1 RefSeq) will be maintained on the website and will still be searchable. In fact, we will keep legacy pages operational for the foreseeable future in case you like the current look and feel.

As always, please let us know of any unusual or unexpected issues and to share your feedback on the new look and feel.

The BLAST server will periodically be unavailable for the next few days to permit updates to be made.


A crowdfunding request for PacBio hamster sequencing

May 29, 2014

The community plans to collect third generation sequencing data (PacBio) on the hamster to help create a new reference assembly. We expect the effort to cost $60,000. We request support from the community. The suggested support level is $5000 per organization, although amounts larger and smaller are welcome. Contributions from U.S. organizations are tax deductible. Our timeline is to collect all data by end of 2014 and to manually correct automated annotations through 2015. Any funds collected over our $60,000 target will support the annotation effort.
Goal: $60,000
Current Commitments: $20,000
