Hi Laetitia,
<div class=""><br class="">
</div>
<div class="">My suggestion would be to check the sanity of the data structure, and to check the dimensionality of cfg.design.</div>
<div class=""><br class="">
</div>
<div class="">Since you handcrafted your numerical data, and don’t give any specifics w.r.t. the metadata (*.dimord, *.freq, *.time, *a.label) of your BigMatdef variable </div>
<div class="">It’s a mismatch between the data and the design that causes the error.</div>
<div class=""><br class="">
</div>
<div class="">I don’t understand why you index the cfg.design variable as if it’s a 4D matrix, typically it’s a row vector (or a matrix with a few rows), with the observations in the columns.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>
<div class="">Jan-Mathijs</div>

<span lang="EN-US" style="font-size: 12pt; font-family: "Times New Roman", serif;" class="">I have a question regarding the function<span class="Apple-converted-space"> </span><b class=""><i class="">ft_freqstatistics</i></b>.<span class="Apple-converted-space"> </span><br class="">

I would like to do statistics on the powerspectrum data (output of the function<span class="Apple-converted-space"> </span><b class=""><i class="">ft_freqanalysis</i></b>) between two conditions (same monkey).<span class="Apple-converted-space"> </span><br class="">
<br class="">
I have the Data Input whose structure corresponds to the output of the function<span class="Apple-converted-space"> </span><i class="">ft_freqanalysis</i>, and the design matrix whose size is the same as the data input (datainput.powspctrm) : size(datainput.powspctrm)

BigMat = NaN(8670,1,182,164);<br class="">
BigMat (1:2078,1,1:91,1:77) = MM25; <span style="color: rgb(0, 176, 80);" class="">% matrix (trials, channel, freq, time) – 1st condition<br class="">

However I still have this error message from Matlab:<span class="Apple-converted-space"> </span><br class="">
"<span style="color: red;" class="">Error using ft_freqstatistics (line 294)<br class="">
the number of observations in the design does not match the number of observations in the data</span>"<br class="">
