Clicking Submit, after several seconds, the IGV result would be listed below.

Note

  1. All tracks are normalized using RPM (reads per million) when generating the wig files.
  2. All tracks were group-autoscaled by datasets. So each track has the same Y-axis range for comparison.
  3. Gene name searching is supported.
