This used to be a problem in earlier versions of Fieldtrip (~ a year ago) but has been fixed. If you want to make sure you can always specify cfg.keepindividual = ‘yes’; and see whether the channels are ordered correctly. Alternatively you could replace the data for one channel in each subject with, for example, ones and see whether ft_timelockgrandaverage produces that channel with a mean of 1 with no variation as well.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Best,<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Jim<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> fieldtrip-bounces@science.ru.nl [mailto:fieldtrip-bounces@science.ru.nl] <b>On Behalf Of </b>van Hoogmoed, Anne H - (annevanhoogmoed)<br><b>Sent:</b> dinsdag 22 oktober 2013 1:00<br><b>To:</b> fieldtrip@donders.ru.nl<br><b>Subject:</b> [FieldTrip] question for using ft_timelockgrandaverage<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Dear all,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’m using ft_timelockgrandaverage to make a grand average of my ERP data. However, the order of the channels is different for some people I want to include in the average.
