January 2006 FreeSurfer Release

Goals

  • Post new 'stable' release, containing reliable auto-segmentation functionality, and bug fixes
  • Make available open-source Freesurfer code (minus Numerical Recipes for C code)
  • Basic automated testing of nightly-build 'dev' code base

Work Items

  • aseg (xiao)

    • working to make aseg work for data originating from different pulse sequences or manufactuers than the training data used to build the atlas. currently, the subcortical atlas is built from Siemens scans, and the aseg results will be quite poor if the input data is from a GE scanner. we have sw that can improve this situation a lot, but it's not very stable, and this cross-sequence option will make the aseg on Siemens data worse.
