Creating Interval Variables

You can create intervals in NeuroExplorer using Edit | Add Interval Variable menu command.

You can also create intervals based on existing Event or Interval variables. Use Edit | Operations on

Data Variables menu command and then select one of the following operations:

MakeIntervals

MakeIntFromStart

MakeIntFromEnd

IntOpposite

IntAnd

IntOr

IntSize

IntFind

Burst analysis creates interval variables (one for each neuron) that contain all the detected bursts as

time intervals.

Interval Variables in NexScript

IntVar[i,1] gives you the access to the start of the i-th interval,

IntVar[i,2] gives you the access to the end of the i-th interval.

For example, the following script creates a new interval variable that has two intervals: from 0 to 100

seconds and from 200 to 300 seconds:

doc = GetActiveDocument()

doc.MyInterval = NewIntEvent(doc, 2)

doc.MyInterval[1,1] = 0.

doc.MyInterval[1,2] = 100.

doc.MyInterval[2,1] = 200.

doc.MyInterval[2,2] = 300.

Limitations

Internally, NeuroExplorer stores the beginning and the end of each interval as a timestamp (see

Spike Trains for more information about timestamps in NeuroExplorer).

Viewers

You can view the intervals of the selected variables in graphical display ( View | 1D Data Viewer

menu command, see figure above).

The intervals (in seconds) are shown in the Intervals sheet of the Data view:
