check the accuracy of the talairach transform by loading it in tkmedit and seeing if it looks reasonable. If it's not wrong, you'll need to specifiy seed points in mri_fill for the pons, callosum and/or the lh and rh white matter.

but when I return to csurf and I try to create the surface, I receive this message when it is filling the white matter:

Could you tell me what to do? Thanks
