Current is version 4.1.9 17/10/11 Bug fix release

A large number of minor patches, corrections and compatibility fixes.

Slice-timing correction in FEAT should be much more accurate.

<span style="font-family: Arial; font-size: medium;">15/05/11 Minor bug fix release
There have been some improvements to the initialisation routines in xfibres
An issue with the -e option in randomise has been resolved - please see the randomise documentation for more details.
A bug in the --peakdist option in cluster has been fixed.</span>

fsl fsl 4.1.6

mwebster@stage.nitrcce.org (Matthew Webster) — Thu, 01 Jul 2010 14:47:00 GMT

An inconsistency with the -s input for fast4 has been fixed.
A bug has been fixed for the randfib option in probtrackx.
There is a new, easy to use tool for reorienting images to match the standard template image orientation (fslreorient2std).
A bug has been fixed in flirt when very high-resolution images are used together with -init matrices.
The input-parsing of feat_model is much improved, courtesy of Jeremy Reynolds.

fsl 4.1.5

4.1.5

fsl 4.1.4

mwebster@stage.nitrcce.org (Matthew Webster) — Tue, 09 Jun 2009 10:56:00 GMT

FIRST has a number of changes - it is recommended to rerun previous analyses with this version .
An issue with abnormal termination of FLAMEO on 32-bit systems has been resolved.
There are minor bug fixes to FEAT and FSLView.
The FAST gui now has an additional bias-field option.
The tbss_sym script has been added to TBSS.
There are some small documentation changes.

fsl 4.1.0

dnkennedy@stage.nitrcce.org (David Kennedy) — Wed, 13 Aug 2008 17:00:00 GMT

* FNIRT - FMRIB's Nonlinear Image Registration Tool. The first release of an accurate and yet fast nonlinear registration tool. This replaces IRTK, and is based on a similar warp field representation, but a) includes relative bias field modelling for improved accuracy and b) is very fast because of explicit computation of the cost function Hessian. FEAT, MELODIC, TBSS and FSL-VBM have all been updated to use FNIRT.
* FEAT v5.98. Various improvements, including FNIRT nonlinear registration, outlier modelling in higher-level analysis and higher-level voxelwise covariates (e.g., for structural confound modelling). A new script feat_gm_prepare makes it easy to process structural data for use as a higher-level voxelwise confound covariate.
* randomise v2.1. Various improvements, including improved handling of confounds, TFCE optimisation for TBSS and parallelisation over multiple computers.
* FAST v4.1 is now the default tissue-type segmentation program, and FAST v3 has been removed from FSL. Hence all programs including SIENA/SIENAX now use FAST v4.
* FIRST subcortical segmentation is now considerably faster, has improved boundary correction and now includes a cerebellum model.
* The outputting of ANALYZE files is no longer supported as the format is now strongly discouraged.

fsl 4.0.4

dnkennedy@stage.nitrcce.org (David Kennedy) — Wed, 01 Aug 2007 4:00:00 GMT

FSL is available precompiled for various different
operating systems (Linux, Mac OS X, Windows). The sources
are also available if you want to compile it yourself.

To unpack a distribution, you need gunzip and tar. First
cd to the directory where you want FSL installed (for
example /usr/local). Then uncompress and untar the
distribution - for example, if you have downloaded the
Mac OS X distribution to your home directory, type

gunzip ~/fsl-*-macosx.tar.gz
tar xvf ~/fsl-*-macosx.tar

For more details, see http://www.fmrib.ox.ac.uk/fsl/fsl/downloading.html

FSL EVALUATION AND EXAMPLE DATA SUITE
There is an evaluation and example data package available
to accompany FSL. This package performs two functions - it
tests whether your FSL tools are working properly, and
provides example data to try running FSL on. The
evaluation of FSL is carried out by a single script which
normally takes between 1 and 2 hours to run (depending on
your computer), testing most of the major tools in FSL on
example data. It compares the output of each test with
precomputed output data supplied with the package, and
reports significant differences as failures. The example
data includes both example input and example output data.
There is a detailed description below of how to analyse the
input data - this is a quick way of starting to use FSL.
