Thanks for the reply, i have plotted the headmodel plot for the 55
electrodes and attached it with this mail
The next step of using the source analysis with calculated grid works
without any problem,
i needed to adjust elec structure according to the radius of the volume
How can i plot the source, i do not have any anatomical MRI at this moment?
Is there a way to see the results from the source analysis using DICS in the
structure of a normal topoplot

Tried the new MSN Messenger? Its cool! Download now.
