norm_BOLD | R Documentation |
Center the data across space and/or time, detrend, and scale, in that order. For dual regression, row centering is required and column centering is not recommended. Scaling and detrending depend on the user preference.
norm_BOLD( BOLD, center_rows = TRUE, center_cols = FALSE, scale = c("global", "local", "none"), scale_sm_xifti = NULL, scale_sm_FWHM = 2, detrend_DCT = 0 )
