<p class=MsoNormal>Hi, I’m looking to compare dipole orientations between
conditions, does anyone know the best way to do this? I’m currently using
BESA to fit dipoles, which gives me an azimuth and elevation angle for each
participant. However, averaging across participants seems problematic – orientations
of 2 degrees and 358 degrees would average to 180 degrees, despite them being
only 4 degrees apart. In addition, dipoles can be flipped in orientation with
no change in residual variance so I would need a method which treats, for
example, 0 degrees and 180 degrees the same.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Does anyone know where this problem has been tackled before?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thank-you,<o:p></o:p></p>
