Arguments

filarray

Filtered array from neuralnetfilter function

statistic

A statistic to compute

progBar

Should progress bar be displayed? Defaults to TRUE. Set FALSE for no progress bar

...

Additional arguments for statistics functions

Value

Returns vector of global characteristics (rows = participants, columns = statistic) or a matrix of local characteristics (rows = ROIs, columns = participants)
