UCSC Single Cell Browser
========================

Funded by the California Institute of Regenerative Medicine and the Chan-Zuckerberg
Initiative https://www.chanzuckerberg.com/.

The UCSC Cell Browser is a viewer for single cell data. You can click on and hover
over cells to get meta information, search for genes to color on and click clusters
to show cluster-specific marker genes, which in turn are clickable again.

For a demo of the browser, see http://cells.ucsc.edu

Usage
-----

After choosing the inputs and executing the tool, once the history item becomes
green, press the View data (eye icon) button, which will open the generated UCSC Cell Browser
interactive site. Press the white on blue "Open Dataset" button.

Troubleshooting
---------------

Depending on the window size when pressing the "View data" button, you might see a black canvas and a diminished panel to the upper left
with the text "Choose cell...". If that is the case, close that panel (click on the cross)
and then choose File -> Open Dataset... and then press the Open Dataset white button.
