Freesurfers,
The new version of Freesurfer, v5.3, is available for download!
Recall from our prior posting that this is intended to replace v5.2, which had a problem with pial and white surface generation affecting thickness and area measures. Users should not use v5.2 for any surface-based studies.
For a list of what v5.3 contains, see this page:
http://surfer.nmr.mgh.harvard.edu/fswiki/ReleaseNotes
If you have already run data through v5.2, and do not want to re-run everything again but only what is necessary, then run the following on your subjects using v5.3:
recon-all -s <subjid> \ -white \ -smooth2 \ -inflate2 \ -autorecon3
This will create new surfaces and surface data. Note that if you choose to re-run the entire stream (-all), the aseg stats will differ from v5.2, but our tests show this difference to be insignificant.
To download v5.3, see this page:

Thank you to everyone who downloaded and tested the beta release of v5.3. We apologize for the hassle and expense of releasing a problematic v5.2. We have improved our testing in the process.
