CHOStart December Update

December 19, 2014

The CHOStart project has generated 84 SMRT cells and 42 GB of genomic sequence data so far. Thanks to your support, we have raised ~30% of the fundraising goal. More details and updates regarding the CHOStart project can be found here.


October 23, 2014

The genome viewer tutorial has been updated with the instructions on how to use JBrowse. The tutorials can be found under the "General Info" tab. Another JBrowse instance has been added as well, which contains the nucleotide sequence of the Chinese Hamster chromosomes (from Brinkrolf K et al).


October 9, 2014

The CHO-K1 genome viewer has been updated from GBrowse to JBrowse, and contains the most up to date annotations (from 2014). The GBrowse instance for the 2012 annotated version of CHO-K1 is still available in the legacy version of the website (linked at the bottom of this page). The updated tutorial for viewing the genomes in JBrowse will be posted shortly.
