<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi all,
<div><br>
</div>
<div>Reading through the discussion list, I see others have also had some issues with creating grand averaged source space time series (ERFs) and subsequent statistical analysis, but I can't see any solutions....</div>
<div><br>
</div>
<div>Questions:</div>
<div>How can I create time series (ERFs) for grand averaged source space data?</div>
<div>And, how can I do cluster analysis<span style="font-size: 10pt;"> on these (yet to be created) grand averaged source space ERFs?</span></div>
<div><br>
</div>
<div><br>
</div>
<div>I have used ft_SOURCEANALYSIS with method 'lcmv' for individual participants to generate source space time series, in data.avg.mom.</div>
<div><br>
</div>
<div>Subsequently I used ft_sourcegrandaverage to combine source space data across subjects. </div>
<div><br>
</div>
<div>However my grand averaged source data.avg only contains 'pow' and no 'mom'. Eg, no time series for the grand averaged source space data. </div>
<div><br>
</div>
<div>As such, I can not do cluster analysis on grand averaged ERFs in source space.</div>
<div><br>
</div>
<div>It appears that ft_sourcestatistics only works with <font size="2">parameters that have not more than one value per </font>grid point<font size="2"> (e.g. pow, nai etc) and is unable to work with ERF time series? Is this true?</font></div>
<div><span style="font-family: Courier; font-size: 10px;"><br>
</span></div>
<div>Can any one help with this?</div>
<div><br>
</div>
<div>Much obliged.</div>
