[Freesurfer] FreeSurfer_volume_Talairach

I assume my question has been skipped. sorry for bothering you again!

Hi,

I am trying to extract Talairach coordinates belonging to white matter volumes (wmparc subregions). Although tkmedit gives the coordinates for volumes, so far I have not found a feasible way by which I could print out the Talairach coordinates for each voxel index belonging to one region (volume) given by ColorLUT, eg lh-wm-parsorbitalis. Is there a way to do this?

For surfaces I found out that each label file contains the list of vertices with RAS coordinates corresponding to one label. Ras coordinates can be converted to MNI, from which we can convert our region into talairach space by applying talairach.xfm. Is there a similiar approach that can be applied to volumes?

I started by converting wmparc into Talairach space by mri_convert.

Could you have a look at fornix segmentation?

Thanks a lot,

Judit Haasz
