Analysis in relation to the path

What do you want to do?

▪In a water maze experiment, calculate the initial heading angle

▪Split the track in a number of segments based on the distance traveled

In a water maze experiment, calculate the initial heading angle

That is, calculate the deviation from the optimal route, for example in the first 15 cm of the swim path.

Specify the track segment From track start until the animal swam 15 cm with a Data profile. Then select the dependent variable Heading to point in an Analysis profile.

1.Smooth the tracks to obtain a swim path less influenced by noise.

2.In the Data profile, in the Components pane, under Nesting, click the button next to Free Interval. Specify the interval “from Track start to Total distance moved >= 15 cm”. See Nest over a Free interval

3.In the Analysis profile, specify the dependent variable Heading to point. Select the center point of the platform. In the Trial Statistics tab, select Mean.

4.Click Statistics and Charts, then Calculate.

Split the track in a number of segments based on the distance traveled

Specify the track segments in the analysis profile.

1.In the Analysis Profile, under Custom Variables, click Free interval. Specify the interval “From Distance moved - Total >=0” “To Distance moved - Total >=100 cm”. Select the option Calculate statistics per interval. In the Trial Statistics tab, select Cumulative Duration.

2.Click Statistics and Charts, then Calculate.

Results

The duration is shown in the columns, for each 1-m segment (interval occurrence 1, interval occurrence 2, etc.).
