<div dir="ltr">Hi Jan-Mathijs,<div>everything started from the fact that I tried to source reconstruct a M1 ERF visual response as a test. The effect at the source level was clearly posterior in the MEG sensors.</div><div>
<br></div><div>However, the source reconstruction gave me a solution with its maximum in the orbitofrontal regions of the brain. This result emerged when I employed the "correct fiducials" extracted from the Neuromag software.</div>
<div><br></div><div>I thought that maybe I had to flip some landmarks to have the effect on the back of the brain. That's why I switched rpa and lpa, with however a more sparse solution. </div><div><br></div><div>I suspect that grid, isotrack points and MEG channels are ok (when I plot them together in Matlab they are well aligned). </div>
<div><br></div><div>Somehow, when I interpolate the power with the realigned brain something goes wrong, and the ft_sourceplot (the one of my previous e-mail) give me the results I described above.</div><div><br></div><div>
I also have to admit that ft_sourceplot in 'neuromag' coordinates shows the brain upside-down.</div><div><br></div><div>N<br><br clear="all"><div><br></div>-- <br><div dir="ltr"><font color="#888888"><div><div style="color:rgb(34,34,34);font-family:arial;font-size:small">
