Hi Holly,
<div class="">You need to ensure that the field RSN_data.label is consistent with the time courses in RSN_data.trial. I suspect that your variable ‘ROI’ is not what it should be.</div>
<div class=""> If there is only a single time course, RSN_data.label should be a 1x1 cell-array with a string in it, e.g. {‘my_virtual_channel’};</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>

I can see that there is only 1 channel in the data structure so I cannot understand why it thinks there are 7. I have tried using a recent version of fieldtrip (20190219) but still get the same error.<o:p class=""></o:p></div>
