After completing the tutorials, you should be able to: After completing the tutorials, you should be able to:. FreeSurfer, Brainstorm high-resolution and Brainstorm vertices Destrieux atlas Displayed in Brainstorm with the original scouts colors left or classified in 6 regions right: Desikan-Killiany atlas Displayed respectively tutlrial Why should I use FreeSurfer? These sessions will be held in the SEA 2.
If the default head surface looks bad, you can try generating another one: From the Matlab command window, you can import the thickness maps with the following call: Low-resolution white matter, processed with reducepatch dreesurfer atlas: These talks have great content.
We have copies of this data stored on servers located in the course room. There is also a FAQ.
The process is fully automatic, but quite resource-consuming. More detailed instructions for setting up the environment and tuning the reconstruction here: Repeat for the other surfaces: FreeSurfer consumes a lot of processor time, memory resources and disk space, so it is recommended to run FreeSurfer on as powerful a machine as you have tutroial. Then you’re prompted for the number of vertices you want in the final cortex surface.
Multi-Modal Integration, Part 1: If you want to remove one or several structures, use the menu “Remove selected scouts” instead. VBM talk Doug Greve 3: This means that some amount of intensity normalization has occurred, but the contrast differences between image examples are easier to see, compared to the original orig. Overview The FreeSurfer tools deal with two main types of data: Comments, bug reports, suggestions, questions Email address if you expect an answer: From the Anatomy side of the database explorer: Attempting to download this data from the public link this link during the course presents excessive and unnecessary load on our network, and likely will fail due to this load.

It also registers the individual cortex surfaces to surface-based anatomical atlases Desikan-Killiany, Destrieux, Brodmann. The talks and tutorials should familiarize you with FreeSurfer’s volume and surface processing streams. After the Course Home page: If you plan to do any of these practical sessions, I do ask that you try and be here for the very first one, Tutorial Housekeepingso that I can pass along some very useful and important information.
Some basic information on text editors can be found here. Increasing this number removes small components that are connected to the head.

There is nothing that can be done with this information at this point, but it will become helpful when projecting the source results from the individual brains to the default anatomy of the protocol, for a group analysis of the results: To access them from the interface: If the final cortex surface looks bad, it means that something didn’t work well somewhere along the FreeSurfer pipeline. Martinos Center for Biomedical Imaging used for a number of procedures including: The tutorials also describe 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.
If something doesn’t look right at this step, for instance if the MRI is not presented with a correct orientation, you should stop this automatic import process and follow the manual instructions in the basic tutorial pages.
