R/nrrd-io.R
Return voxel dimensions (by default absolute voxel dimensions)
nrrd.voxdims(file, ReturnAbsoluteDims = TRUE)
file | path to nrrd/nhdr file or a list containing a nrrd header |
---|---|
ReturnAbsoluteDims | 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.
