FreeSurfer Release Notes
Release Notes cover what's new in the release, and known issues. Download and installation instructions [wiki:DownloadAndInstall are found here], and bug filing instructions [wiki:BugReporting are found here].
Stable v3.0
Stable release version 3.0 is a major release containing many new feature over the prior release version 2.2. Data processed using v2.2 or earlier is not compatible with this new release.
What's New
Sub-cortical segmentation - Each MRI volume voxel is assigned one of 37 possible neuroanatomical labels, including left and and right caudate, putamen, pallidum, thalamus, lateral ventricles, hippocampus, and amygdala. The labeling allows for volumetric measurement of these structures. The segmentation information also improves the ability to create a filled white-matter volume.
Automated filling of ventricles and basal ganglia - Improves the ability to create a filled white-matter volume (which is used in the surface creation process).
Improved skull stripping/cutting plane definition - The needs to conduct manual edits to account for skull-stripping and cutting plane problems is reduced.
New cortical parcellation (Desikan-Killiany) -
Surface-based GLM analysis
Multiple comparison correction (FDR, permutation and monte carlo)
Online tutorial of the Freesurfer work-flow
Simplified distribution download and installation
Support for 64bit Linux and Mac OS X platforms
