January 2006 FreeSurfer Release

Countdown

Feb 1 is in 12 days.

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

A. aseg (xiao)

  1. 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.
  2. testing to optimize the default parameters for the subcortical segmentation.
  3. testing of a new subcortical atlas (asegs should be better than the current atlas).

B. recon-all improvements (doug)

  1. linear pipeline: in recon-all, re-naming of stuff so that files don't get overwritten later in the stream.
  2. test accuracy of aseg and aparc w/ mri_pretess.

C. miscellaneous (doug)

  1. total intercranial volume, using randy's method to align to talairach with skull.
  2. fixing tkmedit so that it implements -overlay-reg-identity properly.
  3. mri_surf2surf - mapping across hemispheres.
  4. mri_glmfit (new version of mris_glm) - mostly just need to document.
  5. mris_preproc - surface-based preprocessor script for mri_glmfit (does not exist but not hard).
  6. correction for multiple comparisons (mri_mcsim and mri_surfcluster).
  7. improve editing of wm with aseg
