scaleSeries {neuroim}

Generic functions to scale (center and/or normalize by standard deviation) each series of a 4D image That is, if the 4th dimension is 'time' each series is a 1D time series.

Description

a logical value indicating whether series should be divided by standard deviation

Examples

bvec <- BrainVector(array(rnorm(24*24*24*24), c(24,24,24,24)), BrainSpace(c(24,24,24,24), c(1,1,1)))
res <- scaleSeries(bvec, TRUE, TRUE)
