Hello FS Gurus,
I would like to export FS labels as seed regions for deterministic tractography
in TrackVis (probabilistic is not appropriate in this investigation). I run
mri_label2vol with “--proj abs -4 0 .1” to try and grow the label into the WM
and exclude GM. While I get a biologically
Hi Sean - Do you mean that the streamlines go through non-brain voxels?
You could you a slightly dilated version of the aparc+aseg as a mask. You
can use bbregister to map it to the subject's DWI space.

Great, I will give that a shot. In the seeding ROI should I combine the gm and
wm labels or is the GM sufficient to encapsulate, say, the superior temporal
gurus GM and WM?

I'd probably try GM plus a (DWI-sized) voxel or so into the WM.

Hi Sean
I think using mris_expand with a negative number is the better way to do
this. Then use the resulting surface for the seed. It should prevent the
surface from passing through itself (which is what you are seeing)
