There are 5 different comparison tests you can use on the input data sets. You can choose to use the mean, standard deviation, or RMS of the entire data set, or you can compare the value or the absolute value of each data point against the threshold value. In the value test, if the given threshold value is negative, then the data are tested to see if they exceed it in the negative sense, i.e. are smaller than the threshold.
Input data sets can be any GraphType objects. That means they can contain multidimensional data arrays. All elements of such arrays are used in constructing the tests.
If the data set is complex, its real part is used for the value and mean tests, while the complex magnitude is used for the absolute value, standard deviation and RMS tests.
If the data set contains more than one dependent data set, only the
first arithmetic data set is used.
If you want the threshold to depend on values calculated elsewhere, you can use the input node window of SigThresh to create an input node for the threshold value.
