This workshop will guide you through several MEG data analysis steps including: data cleaning, frequency analysis, source analysis and network connectivity. Scripts are written in MATLAB using the Fieldtrip Toolbox.
- Step-0 : set-up
- Step-1 : read the continuous data, segment into 2 seconds epochs
- Step-2 : downsample the data to speed up component analysis
- Step-3 : use ICA in order to identify cardiac and blink components
- Step-4 : compute the power spectrum
- Step-5 : compute the forward model
- Step-6 : source reconstruction
- Step-7 : create a pseudo-contrast based on a median split of the epoch
- Step-8 : source reconstruction of the low-high alpha spectral data
- Step-9 : connectivity analysis
- Step-10 : network analysis
