In neuroconductor-devel/fslr: Wrapper Functions for 'FSL' ('FMRIB' Software Library) from Functional MRI of the Brain ('FMRIB')

Resample an Image to Specific Voxel Size

Description

Resample an Image to Specific Voxel Size

Usage

fsl_resample(
  file,
  voxel_size,
  outfile = NULL,
  retimg = TRUE,
  reorient = FALSE,
  opts = NULL,
  verbose = TRUE
)

Arguments

file	Input file to resample
voxel_size	Voxel size (in mm). This should be a scalar number.
outfile	(character) output filename
retimg	(logical) return image of class nifti
reorient	(logical) If retimg, should file be reoriented when read in? Passed to readnii.
opts	options to pass to flirt
verbose	(logical) print out command before running

Value

If retimg then object of class nifti. Otherwise, the output file.

Examples

if (have_fsl()) {
file = mni_fname(mm = 1, brain = TRUE)
est2 = fsl_resample(file = file, voxel_size = 1, retimg = FALSE)
pixdim(est2)
est = fsl_resample(file = file, voxel_size = 1)
pixdim(est)
}
