Return voxel dimensions (by default absolute voxel dimensions)
nrrd.voxdims(file, ReturnAbsoluteDims = TRUE)path to nrrd/nhdr file or a list containing a nrrd header
Defaults to returning absolute value of dims even if there are any negative space directions
numeric vector of voxel dimensions (NA_real_ when missing) of
length equal to the image dimension.
NB Can handle off diagonal terms in space directions matrix, BUT assumes that space direction vectors are orthogonal.
Will produce a warning if no valid dimensions can be found.
Other nrrd:
is.nrrd(),
read.nrrd(),
write.nrrd()
