<p class="MsoNormal">That depends on with what syntax you called ft_freqstatistics: if your data argument is an 1XN cell-array of data structures you need to call it like ft_freqstatistics(cfg, data1{:}, data2{:}), i.e. with the explicit bracket expansion.

<p class="MsoNormal">The issue you are facing, is that you input grandaveraged data into ft_freqstatistics, which does not contain the individual subject estimates anymore. So indeed, as you already suspected yourself, there’s something wrong with the input
into the function. Once the individual subject dimension is gone, it is impossible to compute a group-level T-statistic, let alone a corresponding critical value for clustering.<o:p></o:p></p>
