How do I generate CSD transformations from an EEGlab data file?
The general procedure is described in the CSD toolbox tutorial, which is strongly recommended to any researcher before embarking upon the transformation of EEG/ERP data into CSD estimates. However, two excellent example scripts kindly provided by John J.B. Allen showcase how to exploit the EEG montage information included in any EEGlab data file to generate the montage-dependent “Channels × Channels” transformation matrices G and H (EEGlab_Make_G_H.m), and how to use these transformation matrices with individual EEGlab data files, consisting of “Channels × Sample Points × Epochs (Trials)” data matrices, to obtain corresponding CSD data files (EEGlab_Loop_Epochs.m).
