Hi Trippers,<br>
<br>
I have performed dipole fitting on some data and I would like to
identify the anatomical regions in which various dipoles are located
- ie, to make statements of the sort, 'dipole X was (best) localised
to the right superior parietal cortex'. Specifically - I have the
output from ft_dipolefitting which gives positions in the head space
of the individual subjects, and I would like to anatomically label
the dipoles according to the AAL atlas, which is based on the MNI
template brain. <br>
<br>
I *think* what I will need to do is apply some warping of the
subject MRI to the MNI template, and then apply the same warping to
the dipole co-ordinate. However it is not clear to me how to warp a
single point, rather than an entire volume. Is there some fieldtrip
function that could be used for this?<br>
<br>
I do not think the approach detailed in <i><a class="moz-txt-link-rfc2396E" href="http://fieldtrip.fcdonders.nl/example/create_single-subject_grids_in_individual_head_space_that_are_all_aligned_in_mni_space"><http://fieldtrip.fcdonders.nl/example/create_single-subject_grids_in_individual_head_space_that_are_all_aligned_in_mni_space></a></i>
will be much use here, since (if I understand correctly) the
MNI-aligned grid created here would only be used as a starting point
for ft_dipolefitting. In the end a given dipole might not correspond
to any grid point.<br>
<br>
Can anybody advise me on how to set about this?<br>
<br>
Thanks a lot.<br>
<br>
Best,<br>
Tom
