# Analysis of event transitions and sequences

What do you want to do?

▪Calculate transitions between zone visits

▪Analyze bouts of behavior

Calculate transitions between zone visits

For example, how many times did the subject go from zone A to zone B? Or, in a Y-maze experiment, how many times did the subject go from zone A, to B, then C? Or, in a radial maze experiment, how many 8-arm visits were made without any revisits?

1.In the Analysis profile:

For zone alternations (like in a Y-maze test), choose the dependent variable Zone alternation. See Zone alternation

For transitions in general, choose Zone transition and define the sequence (for example, in a radial maze test, Arm 1 > Arm 3 > Arm 5).

Select the sequence of zone visits. If necessary, select more sequences. See Zone transition.

In the Trial Statistics tab, select the statistic Total number.

2.Click Statistics and Charts, then Calculate.

Analyze bouts of behavior

If you define a bout of behavior as a group of events where the interval t between them is lower than a specified limit (t < tmax), you can detect those bouts with the Free intervals function. For example, look for bouts of movement, where single instances of the state Moving are separated by less than five seconds.

In the Analysis profile, choose the dependent variable Free interval.

For an example, see Detect bouts of behavior in Examples of Free intervals in the Analysis profile.
