FLIRT v5.5 - User Guide

INTRODUCTION

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.

For more detail on FLIRT and an updated journal reference, see the FLIRT research web page. If you use FLIRT in your research, please quote the journal reference listed there.

GENERAL ADVICE


TEMPLATE IMAGES

Both linearly and non-linearly generated MNI152 template images (whole head, extracted brain, brain mask and skull) are included in fsl/data/standard, courtesy of the MNI.


NON-LINEAR REGISTRATION

Also see the FSL non-linear registration tool, FNIRT. Note that this requires an initial affine registration to be performed first using FLIRT.
