SPM for Basic and Clinical Investigators

SPM8 for Basic and Clinical Investigators is an intermediate-level, 5-day workshop designed for investigators having familiarity with the fundamental principles of fMRI measurement and design, with at least six months experience in functional neuroimaging data acquisition and analysis.

The strongly interactive workshop will focus on using SPM8 and its extensions for preprocessing, statistical modeling and visualization of data associated with a range of basic and clinical fMRI experimental designs. While the primary emphasis will involve using the core SPM8 programs for these purposes, there will also be extensive discussion of a variety of software tools that extend the power of SPM8. Some of these tools facilitate fMRI quality assurance through artifact detection and mitigation at various analysis stages. Other tools support a variety of data visualization methods, including MRIcron, xjView, FSLview, and FreeSurfer.

As the presentations will include demonstrations and tutorials utilizing SPM8, participants are expected to bring a laptop with MATLAB, SPM8 and MRIcron already installed. Detailed setup instructions can be found here.

Lectures for the Boston course will be held in the 5th Floor Conference Room in the Constutution Inn.
