In neurobase: 'Neuroconductor' Base Package with Helper Functions for 'nifti' Objects

Copy NIfTI Header to an array

Description

Copies slots of a nifti object to an array. This is useful if you're subsetting 4D data and getting an array out

Usage

copyNIfTIHeader(
  img,
  arr,
  drop_slots = c(".Data", "dim_"),
  drop = TRUE,
  onlylast = TRUE,
  warn = TRUE,
  ...
)

Arguments

img	object of class nifti to copy header
arr	array to copy header information
drop_slots	Slots not to copy over from header
drop	Should dropImageDimension be called before returning?
onlylast	if drop = TRUE, passed to dropImageDimension, if only the last dimensions should be dropped
warn	if drop = TRUE, passed to dropImageDimension, for warning print out
...	arguments to pass to nifti

Value

Object of class nifti the size of arr

Examples

img = nifti(img = array(rnorm(10^4), dim=rep(10, 4)), dim=rep(10, 4), datatype = 16)
sub = img[,,,1:3]
copyNIfTIHeader(img, sub)
sub = img[,,,1, drop=FALSE]
copyNIfTIHeader(img, sub) 
copyNIfTIHeader(img, sub, drop = FALSE)
