Averaging period :
Duration over which the average speed will be calculated.
Ranges :
Definitions of speed "ranges".
ranges can be:
of equal width: In this case, the width of the interval must be defined, as well as the minimum and maximum speeds to be taken into account.

variable width: In this case, each interval must be defined.

Example :
Analysis time: 10 minutes.
Averaging time: 1 minute. Equal intervals: width = 5 mm/s.
Step 1: EthoTrack calculates the average speed of the animal over each period: 0 to 1 min, 1 to 2 min, 2 to 3 min, ...., 9 to 10 min.
For example :
|
period
|
average speed
|
speed interval
|
|
0 - 1
|
0.3mm/s
|
0 - 5
|
|
1 - 2
|
2.3mm/s
|
0 - 5
|
|
2 - 3
|
10.2mm/s
|
10 - 15
|
|
3 - 4
|
24.3mm/s
|
20 - 25
|
|
4 - 5
|
11.3mm/s
|
10 - 15
|
|
5 - 6
|
1.1mm/s
|
0 - 5
|
|
6 - 7
|
1.9mm/s
|
0 - 5
|
|
7 - 8
|
14.6mm/s
|
10 - 15
|
|
8 - 9
|
22.5mm/s
|
20 - 25
|
|
9 - 10
|
23.6mm/s
|
20 - 25
|
Step 2: EthoTrack groups the periods during which the average speed belongs to the same speed interval and calculates the percentage of the total time.
For example :
|
speed interval
|
periods
|
Duration
|
% Test duration
|
|
0 - 5
|
0 - 1
1 - 2
5 - 6
6 - 7
|
4 minutes
|
4 / 10 = 40 %
|
|
10 - 15
|
2 - 3
4 - 5
7 - 8
|
3 minutes
|
3 / 10 = 30 %
|
|
20 - 25
|
3 - 4
8 - 9
9 - 10
|
3 minutes
|
3 / 10 = 30 %
