FLIRT is an example of a software that performs linear registration, meaning that it will translate, rotate, zoom and shear one image to match it with another. Sometimes the differences between subjects are such that the linear transform is not sufficient to achieve good registration. The local deformations permitted by a non-linear method may .

FSL is a comprehensive library of analysis tools for FMRI, MRI and diffusion brain imaging data. It runs on macOS (Intel and M1/M2), Linux, and Windows via the Windows Subsystem for Linux, and is very easy to install. Most of the tools can be run both from the command line and as GUIs ("point-and-click" graphical user interfaces).-d: FSL design matrix (as created by the Glm GUI). --useReconNative: Reconstructs the meshes in the native space of the image. For vertex-wise stats need to also use --useRigidAlign. --useReconMNI: Reconstructs the meshes in MNI space (native space of the model).

The main options are: an input (-in) and a reference (-ref) volume; the calculated affine transformation that registers the input to the reference which is saved as a 4x4 affine matrix (-omat); and output volume (-out) where the transform is applied to the input volume to align it with the reference .FLIRT matrices are defined in terms of *FSL coordinates*, which is a coordinate system where voxels are scaled by pixdims, and with a left-right flip if the image ``sform`` has a positive determinant. FLIRT matrices thus encode a transformation from source image FSL coordinates to reference image FSL coordinates. """ import numpy as np from .FLIRT transformation matrices are affine matrices of shape (4, 4) which encode a linear transformation from a source image to a reference image.
