5.5.8. Operations on Variables Functions
The following operations on variables functions are available in NexScript
Function Description
Rename Renames the specified variable.
Join Creates the new event that contains both the timestamps of var1
and the timestamps of var2.
Sync Creates the new event containing all the timestamps of var1 that
are in the intervals [var2+from, var2+to].
NotSync Creates the new event containing all the timestamps of var1 that
are NOT in the intervals [var2+from, var2+to].
FirstAfter Creates the new event containing the first timestamp of var1 in
each of the intervals [var2+from, var2+to].
FirstNAfter Creates the new event containing the first N timestamps of var1
after each of the var2 timestamps.
LastBefore Creates the new event containing the last timestamp of var1 in
each of the intervals [var2+from, var2+to].
IntervalFilter Creates the new event containing all the timestamps of var that
are in the intervals of the intervalVar.
SelectTrials Creates the new event containing the specified timestamps of
variable var. selectList can contain comma-separated indexes or
ranges of timestamps for example: 1,3-5,10.
SelectRandom Creates the new event containing randomly selected timestamps
of variable var.
SelectEven Creates the new event containing even (2nd, 4th, etc.)
timestamps of variable var.
SelectOdd Creates the new event containing odd (1st, 3rd, etc.) timestamps
of variable var.
ISIFilter Creates the new event containing timestamps of the variable var
that have preceding interspike intervals larger than min ISI.
FirstInInterval Creates the new event. For each interval of intervalVar, the first
var timestamp in this interval is copied to the result.
LastInInterval Creates the new event. For each interval of intervalVar, the last
var timestamp in this interval is copied to the result.
StartOfInterval Creates the new event. Copies the start of each interval of
intervalVar the result.
EndOfInterval Creates the new event. Copies the end of each interval of
intervalVar the result.
MakeIntervals Creates new interval variable with intervals
[varTimestamp+shiftmin, varTimestamp+shiftMax].
MakeIntFromStart Creates new interval variable. For each timestamp (tstart) of
intStartVar, it looks for the first timestamp (tend) of the intEndVar
after tstart. If tend is before the next timestamp of intStartVar, it
adds the interval [tstart+shift1, tend+shift2] to the result.
MakeIntFromEnd Creates new interval variable. For each timestamp of the
