19 August 2009 -- UCSF FreeSurfer? data use recommendations:
Freesurfer version 4.3.0 for cross sectional data (UCSFFSX) and FS version 4.4.0 for longitudinal data (UCSFFSL) are now available for download and are strongly recommended for use. The latest data is located under Clinical, Biomarker, Imaging and Related Metadata, in the numeric summary dataset here:
http://www.loni.ucla.edu/ADNI/Data/
note: This data consists of volumetric numerical summaries for each subject that was run through
FreeSurfer?. Our in-house quality control ratings will be added to the numerical summaries as soon as they are complete. Additionally, we are currently working on a method to upload the post-processed masks to LONI; an announcement will be posted here as soon as these are made available.

After completion of UCSFFRESFR analysis with FS version 4.1.0, we determined that there seemed to be a bias for increasing rates of change, and thus the rates of change reported in this data set are spuriously elevated. We strongly suggest NOT to use this data set, and rather use data which we have run with FS version 4.3.0 and will be uploaded in mid-late June 2009. A full longitudinal data set with the latest version of longitudinal FS version 4.4.0 will be uploaded to ADNI by July 15 2009, and we strongly suggest using this data.
