afni_3dvolreg: Perform Volume Registration for Motion Correction

In neuroconductor-devel/afnir: Wrapper Functions for 'AFNI' (Analysis of Functional 'NeuroImages')

Description

Performs Volume Registration for Motion Correction on an NIfTI file or nifti using 3dvolreg

Usage

afni_3dvolreg(file, interpolation = c("Fourier", "heptic", "quintic",
  "cubic", "linear"), rp_file = NULL, full_motion_file = NULL,
  opts = "", retimg = TRUE, ...)

volreg(...)

Arguments

file	file or nifti object
interpolation	interpolation done after realignment.
rp_file	filename of motion parameter output, which should have columns: roll = rotation about the I-S axis (degrees) pitch = rotation about the R-L axis, (degrees) CCW yaw = rotation about the A-P axis (degrees) dS = displacement in the Superior direction (mm) dL = displacement in the Left direction (mm) dP = displacement in the Posterior direction (mm)
full_motion_file	filename of full motion parameter output, including fields as in rp file, but also brik indices and root mean squares
opts	Additional options to pass to 3dvolreg
retimg	Should an image be returned?
...	additional arguments to readnii

Value

If retimg then object of class nifti. Otherwise, the outfile argument is returned (or a temporary filename)
