Hello,
I'm looking at fine changes in MEG forward leadfields and would like to use the
164k meshes in each subject (I know 164k vertices are overkill, but I need this
high res rendering for one of my figures). I'm interested in the actual
original location of individual vertices in the brain in subject-specific
ACPC-aligned headcoordinate space. I don't want any non linear spatial
transformation applied to the mesh.
So I would like to use the 164k mesh with coordinates without the nonlinear
transformation that (as far as I understand) was applied to all the 164k_fs_LR
files. Is there an easy way to revert the non linear transformation?
I would then use the file {Subject}.{Hemi}.midthickness.164k_fs_LR.surf.gii and
apply the inverse transformation,
Alternatively, is there a way to easily downsample
{Subject}.{Hemi}.midthickness.native.surf.gii to 164k vertices? is this then in
subject-specific ACPC-aligned headcoordinate space? how could I move to that
space?
Does that make sense?
Many thanks,
Max
