But am I right in thinking this command will simply accept a matrix with rows=samples... And no provision for events or epochs? So I would have to firstly elect data by each stimulus type, and then export a version of [EEG.data] where all the epochs in the 3rd dimension were concatenated together, and then hope that there is some way to re-segment in cartool...</div><div><br></div><div>Then I searched my archives of eeglablist emails for a dim memory - the writecnt function. This looks like it might do the trick, except that my data are already epoched, and there is no equivalent "writeeeg" to write a neuroscan epoched *.eeg file...</div><div><br></div><div>Any tips - has anyone opened ICA-filtered epochs from EEGLAB in Cartool before?</div><div><br></div><div>Thanks!</div><div><br></div><div><br></div><div><br></div><div>-hamish0</div><div><br></div><div><br></div></div></body></html>
