Connectome dataset for the publication: 'The relationship between EEG and fMRI connectomes is reproducible across simultaneous EEG-fMRI studies from 1.5T to 7T' Wirsich et al. 2021, NeuroImage, doi: 10.1016/j.neuroimage.2021.117864 Data description eeg-fmri_connectomes_$atlas$_scrubbed_$dataset$.mat datasets with filename truncTo4min58_5s hold static connectivities based on timeseries truncated to 4min58.5s. All other datasets are based on static connectivities derived from the total session timeseries. subj: subject subj.name: name of the subject subj.sess: session subj.sess.sess_name: name of the session subj.sess.fMRI: vector of upper triangular of fMRI connectivity subj.sess.EEG: EEG connectomes subj.sess.EEG.name: name of connectivity measure used (imaginary part of the coherency: iCoh, amplitude envelope correlation (orthongonaliyzed): hilb_Ortho, Amplitude envelope correlation (not orthongonaliyzed): hilb_noOrtho) subj.sess.EEG.bands: EEG frequency bands subj.sess.EEG.bands.name: name of frequency band (delta, theta, alpha, beta, gamma) subj.sess.EEG.bands.name.conn: vector of upper triangular of EEG connectivity subj.atlas: Atlas subj.atlas.name: name of atlas used (Desikan or Destrieux) subj.atlas.regions: number of regions Use the following code to convert connectivity vectors to a connectivity matrix for atlas(1): regions = length(atlas(1).labels) mrtx = zeros(regions); count = 1; for r1 = 1:regions-1 for r2 = r1+1:regions mrtx(r1, r2) = subj.sess.fMRI(count); mrtx(r2, r1) = mrtx(r1, r2); count = count + 1; end end atlas_labels.mat atlas.name: atlas Name atlas.labels: labels of each atlas region
