FreeSurfer Work Flows

FreeSurferWorkFlows describes processing workflows for FreeSurfer. An overview of the major processing steps taking place in a standard FreeSurfer workflow are described in this document: [http://surfer.nmr.mgh.harvard.edu/docs/ftp/pub/docs/FSL_anatomical_stream.pdf Building Anatomical Models with Freesurfer].

For more detail you can view the Morphometry and Reconstruction section of the FsTutorial: FsTutorial/MorphAndRecon

FreeSurferWorkFlows include:

Recommended:

• BasicReconstruction (fully automated)

• TroubleshootingReconstruction (where manual intervention is required when the automated programs fail)

• HistoricalReconstruction (semi-automated, with routine manual edits of the segmented white matter volume)

• SubcorticalSegmentation (already included in Basic workflow, but must be done separately if using Historical workflow)

Use the BasicReconstruction workflow if you are just starting to process data. Use the HistoricalReconstruction workflow if you have already processed large amounts of data using previous versions of FreeSurfer which required manual edits, and you do not wish to reprocess them with the Basic workflow.

• IMPORTANT: Whichever workflow you choose, be sure to process all your study's data using the same workflow.
