Hi,
We are planning to do shape analysis of the corpus callosum. In order to do that we need the coordinates (x,y,z) of the voxels comprising the cc in the subcortical segmentation.
We are using FS v. 3.0.2. The corpus callosum info in the aseg.stats shows all zeros for all subjects, does that mean that cc is not identified in 'aseg.mgz' in FS v. 3.0.2? There is corpus callosum info in the aparc.stats files but we assume that's from the cortical surface reconstruction and therefore not appropriate.
Do any of the later versions of FS have the information we need in order to identify the corpus callosum in the volumetric segmentation? We know that v. 4.0.0 (and up) have a corpus callosum segmentation with five labels in 'aseg.mgz'. Does that mean that if we redid the recons with this version we would be able to obtain the coordinates of the cc?
Is there any way to get this info from the data recon'ed with v3.0.2?
Thank you!
yours, Dr. Lars M. Rimol
