On this page we provide a list of plugins, extensions, toolboxes, templates and atlases that have been created by FMRIB and other groups, which are relevant to users of FSL. To add a new entry, please email details to fsl@fmrib.ox.ac.uk
FLICA (FMRIB's Linked Independent Component Analysis) is an exploratory analysis tool designed to automatically find structured components that cross multiple modalities of group data (e.g. TBSS, VBM, Freesurfer, etc).
FSLNets is a set of simple MATLAB scripts for carrying out basic network modelling from (typically FMRI) timeseries data. This beta-version package requires you to have various other software than just FSL, such as MATLAB, and for now is not bundled as part of FSL.
A miscellaneous set of useful FSL shell scripts.
featquery percent change calculation
This guide describes how featquery calculates percent change and how for certain types of studies a different procedure is necessary to calculate interpretable percent changes.
A matlab based power calculation tool that has been developed for the calculation of power for future group fMRI studies utilizing the analysis results from previous fMRI studies.
This approach to spatial clustering has some important properties (independence of cluster shape and total variance), carries out density estimation in 3D and shrinks the set of voxels to their densest regions.
DTI-TK is a spatial normalization & atlas construction toolkit, designed from ground up to support the manipulation of diffusion-tensor images (DTI) with special cares taken to respect the tensorial nature of the data. It implements a state-of-the-art registration algorithm that drives the alignment of white matter (WM) tracts by matching the orientation of the underlying fiber bundle at each voxel. The algorithm has been shown to both improve WM tract alignment and to enhance the power of statistical inference in clinical settings.
Interoperability with FSL is straighforward using the fsl_to_dtitk script that converts a set of V[1-3] and L[1-3] dtifit files into the NIfTI tensor format that DTI-TK uses.
This FLIRT/FNIRT extension applies angular q-space interpolation when registering 4D diffusion-weighted MRI volumes. The scripts can simply switch to single volume registration and to default FLIRT/FNIRT functionality.
Groups/people working on GPU (etc) accelerations, or parallelisations, of FSL
We're creating this list so that the various groups who have expressed an interest in working on accelerating aspects of FSL through the use of GPUs (or similar) can co-ordinate their efforts with each other if they wish.
Can we suggest that people email fsl@fmrib.ox.ac.uk with a one-line summary of what they are working on and what progress/results they have made.
