Filter track by condition (analysis)

This analysis allows you to leave only those sites which satisfy given JavaScript condition. Each site from the track is tested against the condition.

• Input track – track you want to filter
• Condition – JavaScript expression which must return true if condition passed or false otherwise. The following variables are available:
  • seq – sequence or chromosome name,
  • from – site start position,
  • to – site end position,
  • strand – site strand (0 = unknown, 1 = n/a, 2 = +, 3 = −, 4 = both),
  • type – site type,
  • properties – additional track-specific properties
• Output track – specify the path where to store the result
