normalizeWS: WhiteStripe intensity normalization.

In neuroconductor-releases/RAVEL: Removal of Artificial Voxel Effect by Linear Regression

Description

WhiteStripe intensity normalization.

Usage

normalizeWS(input.files, output.files = NULL, brain.mask = NULL,
  WhiteStripe_Type = c("T1", "T2", "FLAIR"), writeToDisk = FALSE,
  returnMatrix = TRUE, verbose = TRUE, ...)

Arguments

input.files	Vector of filenames for the input images. Must be NIfTI files.
output.files	Optional vector of filenames for the output images. By default, will be the input.files with suffix "WS".
brain.mask	Filename for the brain binary mask specifying the template space brain. Must be a NIfTI file.
WhiteStripe_Type	What modality is used for WhiteStripe? Should be one of T1, T2 or FLAIR.
writeToDisk	Should the normalized scans be saved to the disk?
returnMatrix	Should the matrix of normalized intensities be returned?
verbose	Should messages be printed?
...	additional arguments to pass to whitestripe

Value

if returnMatrix is FALSE, no value returned, but WhiteStripe-normalized images are saved. If returnMatrix is TRUE, WhiteStripe-normalized images are saved and a matrix of normalized intensities is returned.
