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:
