Dear Fieldtrippers,
<div><br>
</div>
<div>I have a sample of 350 trials for one condition, but for statistical analysis reasons I would like to split randomly this sample in two and average these two parts.</div>
<div><br>
</div>
<div>so, I used the "randsample" matlab function which seems to work very well and then I averaged this selected sample:</div>
<div><br>
</div>
<div>
<div style="margin: 0px; font-size: 10px; font-family: Courier; "> randomhalf = randsample(cleandata.trial, 175);</div>
<div style="margin: 0px; font-size: 10px; font-family: Courier; "> avgFCMiddleRing = ft_timelockanalysis(cfg, randomhalf);</div>
<div><br>
</div>
<div><br>
</div>
<div>However, I have the following error message :</div>
<div><font color="#e32400"><br>
</font></div>
<div>
<div><font color="#e32400">Error using ft_checkdata (line 366)</font></div>
<div><font color="#e32400">This function requires raw or comp data as input.</font></div>
<div><font color="#e32400"><br>
</font></div>
<div><font color="#e32400">Error in ft_timelockanalysis (line 105)</font></div>
<div><font color="#e32400">data = ft_checkdata(data, 'datatype', {'raw', 'comp'}, 'feedback', 'yes', 'hassampleinfo', 'yes');</font></div>
</div>
<div><br>
</div>
<div>Does anyone have a solution to fix the problem?</div>
<div><br>
</div>
<div>Thank you very much!</div>
