Dear all, Some 4D system used a synchronization pulse for external EEG machine that adds the value of 8192 to the trigger channel. This is annoying, perturbing the list of triggers (lost of triggers, unwanted triggers). We found that this has been taken into account in the read_trigger.m program for the Glasgow site. Would it be possible to add the site 'Marseille' along with the site 'Glasgow' line 179 of ft_read_event.m? That will be very helpful for us. Thanks a lot Our best, Sophie and Jean-Michel (jean-michel.badier(at)

Sure, no problem. Shall I add the feature and can I leave the testing over to you? JM
