+<h2>Oct. 11, 2019 &nbsp;&nbsp; New "group auto-scale" option</h2>
+<p>
+A new &quot;group auto-scale&quot; option is now available for signal tracks
+collected together in composites. The original auto-scale setting, which is still
+available, acts to auto-scale each track individually inside a composite group.
+With the new &quot;group auto-scale&quot; setting, all of the tracks within the
+composite will scale to the track with the highest auto-scale value viewed in the region.</p>
+<p>
+For example, below is a side-by-side image of two views of the same data from
+a selection of cell lines within a composite of related RNA-seq experiments. On
+the left is the original &quot;auto-scale to data view&quot; setting, where each track is
+auto-scaled to appear at each track's highest value. And on the right is
+the new &quot;group auto-scale&quot; setting for the same RNA-seq data where all tracks
+are scaled against the one track that has the highest value (67215 for IMR9 cell TAP + 1)
+in the region.</p>

+</p>
+<p>
+While the original auto-scale setting on the left has the advantage of showing any
+available data calibrated to each track's maximum, the new &quot;group auto-scale&quot;
+setting on the right quickly draws attention to the track with the highest signal
+within the composite group.</p>
+<p>
+The new &quot;group auto-scale&quot; setting can be found for signal tracks within a
+composite under the &quot;Data viewing scaling:&quot; options.

 <h2>Oct. 9, 2019 &nbsp;&nbsp; Expanded CRISPR track released for human (hg38/GRCh38)</h2>
 <p>
 We are pleased to announce the release of an expanded
  <a href="../cgi-bin/hgTracks?db=hg38&hideTracks=1&knownGene=pack&crisprAllTargets=pack&position=chr7:116397500-116398000" target="_blank">CRISPR Targets track</a> for the human
 hg38/GRCh38 assembly. This track shows the DNA sequences targetable by CRISPR RNA guides
 using the Cas9 enzyme from S. pyogenes (PAM: NGG) over the entire human genome. CRISPR target
 sites were annotated with predicted specificity (off-target effects) and predicted efficiency
 (on-target cleavage) by various algorithms through the tool
 <a href="http://crispor.tefor.net/" target="_blank">CRISPOR</a>. The target sequence of the guide
 is shown with a thick (exon) bar. The PAM motif match (NGG) is shown with a thinner bar.
