bigGenePred Format Now Supported in the Genome Browser
We are pleased to announce that the UCSC Genome Browser now supports data in
bigGenePred format. bigGenePred format stores annotation items that are a linked collection
of exons, much as BED files do, but bigGenePred has additional information
about the coding frames and other gene specific information. bigGenePred files are created initially
from BED-type files with some extra fields, using the program bedToBigBed with a special
AutoSQL file that defines the fields of the bigGenePred. The resulting bigBed files are in an
indexed binary format. The advantage of these bigBed files is that only portions of the files
needed to display a particular region are transferred to UCSC. So for large data sets,
bigBed is considerably faster than regular BED files.
This new format is available for use in custom tracks and data hubs. For more information
about bigGenePred, please see our
bigGenePred Track Format help page.

New Tarsier (tarSyr2) Assembly Now Available in the Genome Browser
We are pleased to announce the release of a Genome Browser for the September 2013
assembly of tarsier, Tarsius syrichta (WashU Tarsius_syrichta-2.0.1,
UCSC version tarSyr2). The whole genome shotgun assembly was provided by
There are 337,189 scaffolds with a total size of 3,453,864,774 bases.
Bulk downloads of the sequence and annotation data are available via the Genome
page. These data have
specific conditions for use.
The tarsier (tarSyr2) browser annotation tracks were generated by UCSC and
collaborators worldwide. See the
Credits page for a detailed
list of the organizations and individuals who contributed to this release.
