Filtering Tracks Data (TEST)

Use the Filter command in the Track Label context menu to restrict which tracks are displayed:

  • Annotation-based (string) filters

    rbrowser:get('name') == 'YTHDF2'  // Show only tracks with gene name “YTHDF2”
rbrowser:get('type') == 'CDS'     // Show only CDS-region tracks

  • Value-based (numeric) filters 

      rbrowser:get('score') > 10        // Show only signals with score > 10
