We tried to run ft_freqstatistics for previously calculated grandaverages over subjects in two conditions. However, we are not sure how to specify cfg.neighbours. The grandaverage datasets in the fieldtrip tutorial contain a gradiometer structure, which is probably used to prepare neighbouring channels. When we run ft_freqgrandaverages on our data, this grad structure disappears because it cannot be averaged over subjects. Thus, we were wondering if there is a way to keep the gradiometer information in the averaged data or to append an example grad structure later on?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB style='font-size:9.0pt;font-family:"Verdana",sans-serif'> <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB style='font-size:9.0pt;font-family:"Verdana",sans-serif'>We appreciate any suggestions on that matter. </span><span style='font-size:9.0pt;font-family:"Verdana",sans-serif'>Thank you in advance!<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Verdana",sans-serif'> <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:9.0pt;font-family:"Verdana",sans-serif'>Best<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Dr Conny Quaedflieg & Hanna Stoffregen </p><p class=MsoNormal>Hamburg University </p></div></body></html>
