<div dir="ltr">Dear all,<div><br></div><div>I tried to use fieldtrip to generate a source space and calculate lead field matrix. I found that the dipoles in the source space has x, y, z orientations. Is it possible to generate a source model where the dipole is perpendicular to the cortex surface? </div>
<div><br></div><div>Actually this can be very helpful, since it will reduce the unknown variables and make the inverse problem easier to solve. Also, there are some inverse algorithms which require the dipole to be perpendicular to the cortex surface.</div>
