This also goes for the mri used for the interpolation. You should use an MRI volume that has a transformation matrix attached to it that transforms from voxel space into CTF coordinate system, rather than into MNI space. The result of a faulty interpolation would lead among others to the x and y axis being exchanged. I think you should look into this direction for a solution. </div><div>By the way, (5,2,3) is indeed in the right hemisphere, but how it shows up on the screen depends on whether the anatomy is shown in radiological or neurological convention.</div><div><br></div><div>Best,</div><div><br></div><div>Jan-Mathijs</div><div><br><div><div>On Mar 26, 2012, at 6:45 PM, Kathrin Müsch wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi Fieldtrip users,<div><br></div><div>I am trying to apply a beamformer to simulated data to check whether my headmodels are correct. While ft_dipolefit localizes the dipole in the original position, the beamformer results in a source at a totally different position (see figure 1). I kept everything as similar as possible to the example scripts (forward simulation & dipole fit, forward simulation & beamformer) but used individual gradiometer positions, grid and volume of a single subject (CTF space) and plotted the source in a template grid (SPM space). If I run the dipolesimulation with the individual gradiometer structure and the template headmodel vol and template grid, the dipole and the source result in the same position, although the grad and vol are not in the same coordinate system (figure 2). And importantly, shouldn't the dipole be in the right hemisphere anyway with the coordinates 5/2/3? I appended the code below.</div><div><br></div><div>Could the different coordinate systems lead to the inconsistent results of dipolefitting and beamforming?
