FreeSurfer Tutorial and Workshop

Overview

The FreeSurfer tools deal with two main types of data: volumetric data (volumes of voxels) and surface data (polygons that tile a surface). The talks and tutorials should familiarize you with FreeSurfer's volume and surface processing streams, the recommended workflow to execute these, and many of their component tools. The tutorials also describes some of FreeSurfer's tools for registering volumetric datasets, performing group analysis on morphology data, and integrating multi-modal output with FreeSurfer (overlaying color coded parametric maps onto the cortical surface and visualizing plotted results). After completing the tutorials, you should be able to:

• perform surface reconstructions;
• generate subcortical segmentations;
• fix errors encountered during the volume or surface processing;
• overlay functional data onto surfaces;
• perform group analysis of structural (e.g. thickness) and functional data.

Course Outline

During the tutorial sessions, you will be shown a variety of command strings on the tutorial wiki pages. Only those that appear between lines should be copy-and-pasted into the terminal for this tutorial. Those commands appear like this:
