10 October 2011 - Updated Yeast Browser Released
We are happy to announce an updated Yeast Genome Browser for
Saccharomyces cerevisiae, sacCer3. The April 2011 Saccharomyces cerevisiae
genome assembly (Saccharomyces cerevisiae S288c assembly from Saccharomyces Genome
Database (GCA_000146055.2)) was produced by the Saccharomyces Genome Database (SGD™) project.
Chromosomes available in this assembly: chrI, chrII, chrIII, chrIV ... etc ... chrXVI,
and chrM. See also: SGD™ genome snapshot/overview.
Downloads of the yeast data and annotations may be obtained from the UCSC
Genome Browser FTP server or
The S. cerevisiae annotation tracks were generated by
UCSC and collaborators worldwide.
We'd like to thank the Saccharomyces Genome
Database (SGD™). The S. cerevisiae Genome Browser and annotation tracks were produced by
Hiram Clawson, Greg Roe, and Steve Heitner. See the Credits page for a detailed list of the organizations and individuals who
contributed to this release.

New Navigation and Display Features
We've added several new features to the Genome Browser
that make it easier to quickly configure and navigate
around in the browser's annotation tracks window.
Automatic image resizing: The first time the annotation
track window is displayed, or after the Genome Browser has
been reset, the size of the track window is now set by
default to the width that best fits your Internet browser
window. If you subsequently resize your browser window,
you can automatically adjust the annotation track image
size to the new width by clicking the resize button
under the track image. The default width can still be
manually overridden on the Track Configuration page.
Scrolling left or right in the track window: You can now
scroll (pan) horizontally through the tracks image by clicking
on the image, dragging the cursor to the left or right,
then releasing the mouse button. The view may be scrolled
by up to one image width.
Improved drag-zoom navigation: The browser's
"drag-and-zoom" feature lets you quickly zoom to a
specific region of interest on the annotation tracks image.
To define the region you wish to zoom to, depress the shift
the mouse button on one edge of the desired zoom area
(which can be anywhere in the tracks window),
drag the mouse right or left to highlight the
selection area, then release the mouse button.
The annotation tracks image will automatically zoom to
the new region. The Genome Browser still supports the
earlier implementation of this feature, which restricted
the click-drag to the Base Position track area of the image,
but did not require the shift key to be pressed.
Reordering groups of tracks:
You can now vertically reposition an entire group of
associated tracks in the tracks image (such as all the
displayed subtracks in a composite track) by clicking and
holding the gray bar to the left of the tracks,
dragging the group to the new position, then releasing
the mouse button. To move a single track up or down, click
and hold the mouse button on the side label, drag the
highlighted track to the new position, then release the
If you haven't yet tried the browser's right-click
menu for quick access to frequently used track
configuration features and functionality, read more

New Feature: Track Data Hubs:
We are pleased to announce a new feature in the UCSC Genome Browser: Track Data Hubs. Track hubs are web-accessible directories of genomic data
that can be viewed on the UCSC Genome Browser alongside native annotation
