Various stuff about fMRI/EEG/MEG statistical analysis...

 

• Up-to-date versions of many of the functions below can also be found on GitHub here: https://github.com/MRC-CBU/riksneurotools

 

Efficient fMRI design

• How to design efficient fMRI experiments
• Matlab function for calculating efficiency of fMRI GLMs: fMRI_GLM_efficiency.m

 

General stats stuff

• Power for detecting interactions (moderations) in experimental and field studies: HTML (or R-markdown)
• Relating three variables using GLM and SEM - as easy as ABC: HTML and Rmd TBC

 

ANOVAs/GLM in SPM/Matlab

• ANOVAs in SPM
• Matlab function for N-way repeated measures ANOVAs: repanova.m
• Matlab function for N-way mixed ANOVAs in SPM5/SPM8: batch_spm_anova.m
• Matlab script for simulating pooled versus partitioned errors: check_pooled_error.m
• Matlab function for generic GLM: glm.m
• Comparing a single patient vs a Group (in SPM)

 

SPM stuff

• SPM Course Slides from 2008
• Some Example fMRI/EEG/MEG SPM5 batch scripts
• Single-subject (1st-level) event-related fMRI analysis in SPM Manual and Data
• Group-based (2nd-level) event-related fMRI analysis in SPM Manual and Data
• Extract data for multiple ROIs from multiple datafiles: roi_extract.m
• Example of Source Localisation of EEG and MEG data in SPM5: Manual and Data (~80MB)
• Reading FIF MEG files into SPM5: click here for more info

 

Datasets

• A multi-subject, multi-modal (T1, BOLD, DWI, EEG, MEG) dataset for methods development: A BIDS version is here: OpenNeuro, but if you want the original version used by Wakeman and Henson, you'll need to use an FTP tool to download from "ftp://ftp.mrc-cbu.cam.ac.uk/personal/rik.henson/wakemandg_hensonrn/" (note 170GB!)

 

Misc

• A Matlab toolbox for Strutural Equation Modelling (developed by Nitin Williams): click here for more info
• Matlab function for calculating NxN functional connectivity between all pairs of fMRI timeseries for N ROIs: rsfMRI_GLM
• Matlab function for detecting artefacts in EEG/MEG data using ICA and (bootstrapped) temporal correlations with EOG/ECG and/or spatial correlations with standard template topographies: detect_ICA_artefacts
• Matlab functions for computing multivariate Distance Correlation measure for fMRI functional connectivity
• Matlab function for computing single-trial fMRI estimates fMRI_multitrial_GLMs.m using LSA or LSS (see Abdulrahman &amp Henson (2016)).
