Hi,<div><br class="webkit-block-placeholder"></div><div>I am struggling with the sourceanalysis of EEG data which was recorded with Biosemi 128 electrodes. the data are visual evoked potentials. the topographies look very good and dipolar. below some code attached.</div><div><br class="webkit-block-placeholder"></div><div>one thing i find suspicious is that the 'avg.pow' field after sourceanalysis contains some negative values ... i reckon this shouldn't be the case.</div><div><br class="webkit-block-placeholder"></div><div>the call to sourceanalysis is very close to calls i did with MEG data yielding good localizations. </div><div><br class="webkit-block-placeholder"></div><div>the greatest potential error source i see is that i use electrode positions from the standard_1005 file in order to use the standard BEM model. this is done by choosing the index from the standard-1005 closest to the biosemi elecrode locations (placed on a sphere). for this i use matlabs <span class="Apple-style-span" style="font-family: Courier;
