# Nesting over Body angle state

Aim

To pick out data collected when the subject was in one of the body angle states: Straight or Bent (with the Bent state which can be further split into Bent counterclockwise and Bent clockwise).

Nesting vs. Nesting over Subjects

Notice the difference when there are multiple subjects in the same arena:

▪To select data of a subject based on the Body angle state of that subject, choose Body angle state under Nesting. See the procedure below.

▪To select data of a subject based on the Body angle state of other subjects, choose Body angle state under Nesting over subjects. There you find the Actors tab where you can specify which subjects (Actors) were in a certain Body angle state. See Nesting over subjects

Procedure

1.In the Data Profile, under Nesting click the button next to Body angle state.

2.In the Body Angle State window:

▪Under Outlier filter, enter an Averaging interval to smooth the body angle values.

▪Under Threshold, enter the angle value that defines the state bent.

▪Under Calculate nesting for, select the Body angle state that defines the intervals.

For details about how Body angle state is calculated, see Dependent Variables in Detail > Body angle state.

3.Click OK. Proceed with step 4 in How to select track segments.
