Hi everyone,
<div class=""><br class="">
</div>
<div class="">I’m trying to revive an old processing script for TFRs on a new computer and am running into an error I can’t seem to track down.</div>
<div class="">I want to run ft_freqanalysis and am trying to use a data file that is the output of a preprocessing script that worked fine. As far as I can tell from the fieldtrip guidance/forum, the data structure should be fine, but I am receiving an error
stating that it needs to be a cell array (among other errors). </div>
<div class=""><br class="">
</div>
<div class="">Any help or guidance is greatly appreciated!</div>
<div class=""><br class="">
</div>
<div class="">For reference, I’ll copy and paste the code that’s creating the error, the errors received, and the data file structure (since this seems to be a source of the error):</div>
