== MEG MasterClass == The MEG Master Class tutorial series combines theoretical discussions with practical sessions on many aspects of MEG data analysis using SPM. Working from the [javascript:void(0);/*1240485543728*/ SPM example pathway ]each processing step is split into a small two hour practical. See links below for individual session notes and worksheets. Please note that these sessions do not cover max filtering of the data set - this can be done as shown at the start of the SPM example pathway script and more details on the processing options are available here. === Session 1. Pre-processing === * Importing raw FIF data Into Matlab. * Spliting in Mags, Grads and EEG data sets. * Reading the Trigger line and extracting the triggers and response codes (also see here). * Epoching. * Resynching to a new starting point. * Filtering. * Artefact rejection. * Contrasts. * Grand averaging. * Inspecting the results - topographies, line plots, meg_viewdata. === Session 2. 3D Sensor SPM's === 3D sensor SPMs can be used for a sensor level analysis and as a guide to establish critical time windows to analyse further. * Generating the files. * Computing the anova. * Interpreting the results. === Session 3. Catch up session - THEORETICAL === * When to take the RMS. * How are bad channels dealt with. * Things to be careful about when you have very uneven trial numbers across conditions (e.g. in an MMN expt). === Session 4. Using ICA for artefact rejection === * How and why to use ICA. * Implementing ICA to extract eye blinks, eye movements and cardiac signals. === Session 5. Source reconstuction - THEORETICAL === * Forward model, choice of inverse solution and associated parameters.
