Uncorrected_length is an analysis export variable available in exported integration analyses.
It reports the length (the horizontal dimension in the plane of the echogram) of a school represented by a region on an echogram (m). It is the length of a box bounding the region calculated using the Distance mode selected on the Schools page of the EV File Properties dialog box.
See Schools detection module algorithms for a mathematical definition.
This variable is exported only if it is selected on the Export page of the EV File Properties dialog box.
