#' The data are fractional Amplitude of Low Frequency Fluctuations (fALFF) (Zou et al. 2008)
#' for Autism Brain Imaging Data Exchange collected resting state functional magnetic resonance
#' imaging (R-fMRI) datasets (Di Martino et al. 2013).
#' This data set in \pkg{GET} contains only a tiny part of the whole brain, namely
#' the region 9002 (the right Cerebelum Crus 1) at slice 23
#' (see Figure 2 in Mrkvicka et al., 2019) for 514 individuals with the autism spectrum
#' disorder (ASD) and 557 typical controls (TC) as specified in the given Group variable.
#' Further the sex and age of each subject is given.

#' @format A list of the \code{curve_set} containing the data,
