However, I am already crashing at the first step, i.e. when running ft_definetrial.<br><br>This is my code:<br>cfg = [];<br>cfg.dataset = 'S01_01.ds';<br>cfg.trialdef.eventtype = 'frontpanel trigger';<br>cfg.trialdef.eventvalue = 1;<br>cfg.trialdef.prestim = .25;<br>cfg.trialdef.poststim = 2.75;<br>cfg = ft_definetrial(cfg);<br><br>It recognises correctly that it's supposed to read the header from S01_01.ds/S01_01.res, but it then tells me that it can't find the file S01_01.meg4 (which is true, because it should be S01_01.ds/S01_01.meg4). I presume this is a pretty common error, but it occurs with two FieldTrip versions that I have downloaded (very recent ones). I am probably missing something very obvious...<br><br>Incidentally, is there no other way to search the FieldTrip email archives than to download a zipped text file for each month of the previous 7 years?!?<br><br>Thanks,<br><br>Tobias<br><br><br><br>--<br>Tobias Overath, PhD<br>UCL Ear Institute<br>University College London<br>332 Grays Inn Road<br>London, WC1X 8EE<br>UK<br><a href="http://www.homepages.ucl.ac.uk/~skgtjto">http://www.homepages.ucl.ac.uk/~skgtjto</a><br><br><br><br><br><br></div></blockquote></div><br><div>
