Introduction to MATLAB for NeuroimagingKRISANNE LITINASUM FMRI LABORATORY

Goals

Become familiar with the MATLAB interface Learn some new programming skills Learn how to make simple simulations of BOLD signals Understand how fMRI data are stored and manipulated Dive into the General Linear Model

Why MATLAB?

Need to manipulate data at lower level Quick and easy – no compiling required Ability to do analysis and generate statistics Many useful built-in functions (math, statistics) Powerful debugging tools Offers several options to visualize data Can be used to make data analysis very efficient (automation,

batches) Take advantage of popular image processing packages (e.g. SPM)

About Programming

Wide range of experience in this class Computers are not smart Frustration The learning curve Worth the effort
