Source localization and connectivity analysis of high-density EEG data. I have published a paper on this data in NeuroImage (https://doi.org/10.1016/j.neuroimage.2019.05.038). Pre-processed data after source localization (ICA) is available on figshare (https://figshare.com/projects/Group-level_cortical_and_muscular_connectivity_during_perturbations_to_walking_and_standing_balance/62582). It includes precomputed connectivity using direct directed transfer function (dDTF).
All code used EEGLAB (version 13.5.4b) run on Matlab 2013a. The EMD-CCA preprocessing requires EMDLAB (http://sccn.ucsd.edu/eeglab/plugins/EMDLAB_Plugin.zip), and connectivity analysis requires the SIFT plugin (https://sccn.ucsd.edu/wiki/SIFT).
