Dear Vladimir & list, Is there a convenient way to specify and invert a series of ECD models off the GUI (in the same way as for 'Imaging' reconstruction with spm_eeg_invert) using the fields of D.inv{i} or will I have to go through spm_eeg_inv_vbecd_gui myself to assemble the required parameters on the priors, number of conditions and number of iterations in order to avoid the GUI loop ? Best wishes, Martin
