FMRIB's Linear Image Registration Tool FLIRT


FLIRT (FMRIB's Linear Image Registration Tool) is a fully automated robust and accurate tool for linear (affine) intra- and inter-modal brain image registration.

FLIRT comes with a main GUI as well as three supporting guis:

  • ApplyXFM - for applying saved transformations and changing FOVs
  • InvertXFM - for inverting saved transformations
  • ConcatXFM - for concatenating saved transformations

3D affine transformation based on paired points


Using a text file containing 3D point coordinates as reference pairs, 3D image stack is transformed.
