Track Summary

Mathematical average for each worm:

ClosedArea/Length/Wavelength/Width

ClosedTrack length/Peristaltic track length
  • Track length: Length of the center point trajectory
  • Peristaltic track length: Length of forward motion - (minus) length of reverse motion (red) over the total number of frames tracked.
  • Absolute peristaltic length: Length of forward motion + length of reverse motion (red) over the total number of frames tracked.

ClosedAmplitude

ClosedSpeed (centerpoint and peristaltic)

centerpoint speed (µm/s): Track length divided by time

Peristaltic speed (µm/s): Absolute peristaltic track length divided by time

ClosedStraight-line distance

Shortest distance between centroids at the beginning and the end of a worm track (trajectory)

ClosedTrack duration

Total time (in seconds) of contiguous tracked frames for a given worm

ClosedTurn count

Number of body bends based on the Turning Report threshold conditions defined in the Bending angle Mid-point analysis.

ClosedDistance traveled forward/in reverse

Total distance the worm travels forward/in reverse.

ClosedNumber of reversals

Total from Reversals analysis

ClosedCumulative reversal or forward time

Total time the worm spends traveling in reverse/forward.

ClosedPirouettes

Number of pirouettes: Number of occurrences when there is a reversal followed immediately by an omega bend.

Pirouette time: Average duration of a pirouette
