Hello,<br>
<br>
Having got through the preprocessing I am now investigating source<br>
reconstruction.<br>
<br>
The information on the web site is very useful. This tutorial page:<br>
<a href="http://fieldtrip.fcdonders.nl/tutorial/minimumnormestimate" target="_blank">http://fieldtrip.fcdonders.nl/tutorial/minimumnormestimate</a><br>
<br>
Refers to Ou, W., Hamalainen, M., Golland, P., 2008, A Distributed<br>
Spatio-temporal EEG/MEG Inverse Solver<br>
<br>
which looks interesting but I wondered if this method was actually<br>
implemented in fieldtrip (or elsewhere). When I look in<br>
minimumnormestimate.m this reference is not listed as one of the<br>
methods implemented. Is it available as a different named method?<br>
<br>
Thanks for any help.<br>
<br>
Robin<br>
