The latest release of the FMRIB Software Library (3.0, October 2002)
is now available for downloading from http://www.fmrib.ox.ac.uk/fsl

There are many additions since the last release (June 2001), the main
ones being:

* FEAT v5:

 - Bayesian multi-subject FMRI analysis: General GLM for higher-level
   analysis (e.g. analysis across sessions or across subjects; paired
   t-tests, three-level groupings etc): FLAME (FMRIB's Local Analysis
   of Mixed Effects). FLAME uses very sophisticated methods for
   modelling and estimating the random-effects component of the
   measured inter-session mixed-effects variance, using MCMC to get an
   accurate estimation of the true random-effects variance and degrees
   of freedom at each voxel.

* MELODIC v2:

 - Probabilistic ICA (PICA) for FMRI. By adding a Gaussian noise model
   to the ICA model, and automatically estimating the dimensionality
   (the number of non-Gaussian components), it is now possible to
   create meaningful Z-statistic maps for each spatial component,
   allowing inference ("thresholding").
 - Inference on the Z-statistic images is carried out with a
   Gaussian/Gamma mixture model (fitted using EM), fitting central
   noise and activation classes; thus alternative hypothesis testing
   is used.

* Interoperation with FreeSurfer and AFNI
