Therefore, you need some way to convert the timestamps from E-Prime to sample numbers. The oxy3/4 file does have time information on the measurement start time, which you could use as an estimate for this (I am not sure right now if you get this information out via oxysoft2matlab, please check and if not I can add it and sent you an updated version of the script. In the meanwhile, take the information directly from Oxysoft). Together with the sample rate of the measurement, you then will get a more-or-less accurate mapping from E-Prime time stamps to measurement time. I am saying “more-or-less accurate”, because the measurement start time is the time you finished the Oxysoft measurement wizard, not necessarily the time of the first incoming sample. So, there might be some tens of milliseconds delay between the start of the measurement and the first sample of the measurement, thereby offsetting the triggers by that amount of time. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:EN-US'>In future, if you use E-Prime, best try to send triggers directly to Oxysoft, so that the events are inserted in the data stream directly. There are several ways possible for this, hardware or software based. If you want to know more, please mail me and I’ll forward the respective instructions.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:EN-US'>With best regards,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:EN-US'>Jörn<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:EN-US'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='mso-fareast-language:EN-US'>PS: you can also read in the oxy3 or oxy4 files directly in FieldTrip using the common FT functions like ft_preprocessing.
