has the potential to greatly facilitate our understanding of regulatory
The data comprising these tracks were generated from hundreds of
experiments on multiple cell lines conducted by labs participating in
the ENCODE project, and were submitted to
the UCSC ENCODE Data Coordination Center for display on the Genome
Faced with the problem of how to display such a large amount of data
in a manner facilitating analysis, UCSC has developed new visualization
methods that cluster and overlay the data, and then display the
resulting tracks on a single screen. Each of the cell lines in a track
is associated with a particular color. Light, saturated colors are used
to produce the best transparent overlay.
Currently, the ENCODE Regulation data are available only on the
March 2006 (NCBI Build 36, UCSC version hg18) assembly of the human

4 Oct. 2007 - ENCODE Genome Browser Released for hg18 Assembly
The ENCODE browser for UCSC human genome assembly hg18
(NCBI Build 36) is now available. You can access the browser
or by clicking the ENCODE link on the Genome Browser
home page, then
selecting the Regions (hg18) item in the sidebar menu on
the ENCODE portal page.
The hg18 ENCODE browser includes 540 data tables in 59
browser tracks that were migrated from the hg17 browser.
The hg17 data coordinates were converted to hg18 coordinates
using the UCSC liftOver process.
To improve the accessibility of the data, related ENCODE
tracks have been gathered into new configuration groupings
("super-tracks") that can be displayed or hidden
using a single visiblity control. We have also reduced the
number of track groups and have modified some of the group
names for clarity.
The following table
summarizes the data currently present in the hg18 ENCODE
|Regions and Genes||2||12||73|
Note that the Variation and Comparative Genomics data were
not lifted during this migration; instead, they will be
replaced by new data. The first ENCODE MSA alignment for
hg18 (TBA) is currently in progress on the UCSC
During the migration, ENCODE tracks with whole-genome
data were moved into the standard browser track
groups. These include the GIS PET and UCSD/LI
TAF1 tracks. Future submissions of whole-genome ENCODE data
will be loaded directly into the standard track groups.
We have expanded the ENCODE downloads site to include
original data for all "wiggle" datasets. These
data files now have filename extensions indicating the
wiggle input format (fixed step, variable step, or

The findings of the ENCODE project have been
released to the public today, the culmination of a
four-year effort to catalog the biologically functional
elements in 1 percent of the human genome. The publications,
which include a group paper in the 14 June 2007 issue of
Nature and 28 companion papers
in the June 2007 issue of
Genome Research, were authored by
researchers from academic, governmental, and industry
organizations located in 11 countries. The Nature
issue includes a pull-out poster featuring a screenshot of
the UCSC Genome Browser displaying a broad range of the
In the press release accompanying the publication
NHGRI Director Francis S. Collins is quoted as saying
"This impressive effort has uncovered many exciting
surprises and blazed the way for future efforts to explore
the functional landscape of the entire human genome. Because
of the hard work and keen insights of the ENCODE consortium,
the scientific community will need to rethink some long-held
views about what genes are and what they do, as well as how
the genome's functional elements have evolved. This could
have significant implications for efforts to identify the
DNA sequences involved in many human diseases."

existing ENCODE data tracks to trim overly-long labels
that were truncated in the display and to facilitate
cross-track analysis. The new label format shows the
submitter and the experiment, followed by the cell line
(in tracks where the data includes only one cell line).
Posted on 6 June 2005 - Stanford Promoters and UVa DNA Replication tracks released
We are pleased to announce the first UCSC Genome Browser
tracks released for the June 2005 ENCODE data freeze:

data (such as conservation scores and elements) to the
UCSC ENCODE ftp site as soon as possible and then notify
Other data, (conservation, trees, etc.)
will be generated based on this dataset.
The following is a summary of data updates from the
The human assembly version remains at hg16 (Jul. 2003).
The mouse assembly has been updated from mm5 (May 2004) to
mm6 (Mar. 2005).
The multiple rat sequences have been replaced by a single
sequence: rn3 (Jun. 2003).
The cow sequences have been updated using an assembly of
BAC-based sequences provided by Baylor College of
Fugu (fr1), macaque (rheMac1), opossum (monDom1),
Tetraodon (tetNig1), Xenopus (xenTro1), and zebrafish
(danRer2) have been added. The macaque sequence was
obtained from a Baylor
College of Medicine assembly that has not yet been
A new NISC species, rfbat
(Rhinolophus ferrumequinum), is now available.
Platypus data from regions
where NISC has not yet generated data were provided by
Jim Mullikin from a preliminary assembly of Washington
University WGS reads.
This freeze includes low-redundancy sequence data from
tenrec, elephant, armadillo, and rabbit. Only one set of
sequences are provided per species/target combination;
where available, NISC data is provided instead of
the 2X assemblies. These data are not yet accessioned at
NCBI, but were made available by the Broad Institute
(rabbit, elephant, armadillo) and Jim Mullikin (tenrec).
Orthology predictions for Fugu were made only by
MAVID/Mercator; predictions for all other assemblies
supported by the UCSC Genome Browser represent a union
with UCSC predictions as well. Because no additional
post-processing was done on the Fugu predictions, they
contain a few very small contigs.
Thanks to the many people, particularly Elliott Margulies
and Daryl Thomas, who made this release possible.
Posted on 24 May 2005 - ChIP-PET/GIS annotation track (Genome Institute of Singapore) released

Posted on 2 Feb. 2005 - Affymetrix ChIp/Chip and PolyA RNA data released
A second set of ENCODE ChIp/Chip data is now available on
the July 2003 human genome assembly:
ChIp/Affy Pol2 Pval
ChIp/Affy Pol2 Sites
These tracks show RNA Polymerase II precipitation and
RNA abundance in retinoic acid-stimulated HL-60 cells at
0, 2, 8, and 32 hours, as measured by Affymetrix tiling
arrays in the non-repetitive ENCODE regions. The
Pval and Signal tracks show values
for each tiled probe; the Sites tracks show
contiguous regions of enrichment.
A new composite track display was developed to
concisely display multiple data sets of similar types, a
common feature of ENCODE data. Each of these new tracks
contains 4 subtracks, one for each time interval. The
subtracks share a single description page and set of
visibility controls. Checkboxes on the track
configuration page allow selected subtracks to be hidden
in the display.
These data were generated and analyzed by Tom Gingeras'
Kevin Struhl's group at Harvard Medical
School. We would like to thank Stefan Bekiranov at

Posted on 5 Nov. 2004 - First ENCODE data tracks in the UCSC Browser
The first datasets submitted for the ENCODE project are
now publicly available:
These tracks are visible in the ENCODE track group of the
July 2003 (hg16) human genome assembly. We would like to
thank the labs of Bing Ren (LI/UCSD), Anindya Dutta (UVA),
Rick Myers (Stanford), and Francis Collins (NHGRI) for
contributing the initial ENCODE data sets.

Posted on 26 Oct. 2004 - Sequence Freeze For Multiple Alignments
We are pleased to release the first "official" sequence
data freeze for the ENCODE multiple sequence alignment
projects. The data formats are described in the
README file, and the sequences and
supporting information is collected in the
The species included in this freeze are as follows:
You will notice that we have worked hard to include a
number of species for which genome-wide sequence data was
already available. The process by which these orthologous
regions were identified is still an area of active
research development, the details of which will be
presented at the upcoming ENCODE meeting at CSHL.
Please note that we have also included a *second* rat
sequence (ratB) in this freeze. RatB represents an
initiative to standardize the quality level of sequences
in the ENCODE regions for species with genome-wide
sequence data. The data were made available just before
our freeze date, so we decided to include both versions of
the rat sequence for now. Eventually these sequences will
likely be rolled into future genome assemblies.
Remember, this is a work in progress, so not all targets
have sequence from all species. And some species/target
combinations may not be complete yet. Progress on the
NISC-generated sequences can be found at the
NISC ENCODE Project: Comparative
Many people have worked very hard to make these data
available. Special thanks to Daryl Thomas, Kate
Rosenbloom and the entire UCSC Team; Greg Schuler and the
NCBI team; Colin Dewey and Lior Pachter; Pam Thomas and
the NISC team; and David Wheeler and the BCM team.
Please send any comments to the
ENCODE MSA Mailing List.

Posted on 24 Jun. 2004 - ENCODE Project Portal Released
We are proud to announce the release of features
in the UCSC Genome Browser that are tailored to
the ENCODE project community, including this home
page to consolidate these resources.
The initial resources include sequences for the current
human assemblies (hg16, hg15, hg13, and hg12), sequence of
the comparative species from
tools for coordinate conversion between human
assemblies, format descriptions for data
submission, and contact information for help with
submitting annotation data and analyses.
Bulk downloads of the sequence and annotations may
be obtained from the ENCODE Project
page. The sequences available here are repeat-masked
versions of the GenBank records.
