    I have two index datasets created with different kinds of event isolation. The second one is created by filtering the first one. How can I get the indices that are in the first and not in the second index dataset?

    Using the FPScript function [b]IndexNot()[/b] and [b]IndexAnd()[/b], you’ll get the indices thar are in the one but not in the other dataset. Here is an example:

    [code]
    Dim aa, bb, cc, dd

    aa = {1,3,5,7, 11, 4, 34}
    bb = ValuesInInterval(aa, 0, 10, EVENT_INDEX)
    cc = ValuesInInterval(aa, 0, 5, EVENT_INDEX)
    dd = IndexNot(cc, NumberOfValues(aa))
    IndexAnd(bb, dd)
    [/code]

    The variable bb contains the indices of the values within the interval 0 to 10. The variable cc contains the indices of the values within the interval 0 to 5.
    Use the [b]IndexNot[/b] function to get all indices of the values which are not in the interval 0 to 5. The result of the [b]IndexAnd[/b] function is a data series with the indices which appear in both arguments. In this case the result is a data series with the indices of values within the interval ]5,10].
