Hi Peter,

1) Nope there is no consistent feature or artifact in these brains.
2) Currently we nudge the two un-talirached datasets (i.e., structural and functional) so they are overlaid. Then I use @auto_tlrc on the anatomical and then use @auto_tlrc on the functional. It is following this @auto_tlrc step that the two datasets (structural and functional) fall out of alignment. I have not used the align_epi_anat.py script. Are you suggesting that it would be better to first use @auto_tlrc on the structural and then use the align_epi_anat.py on the functional (i.e., rather than use the @auto_tlrc on the functional)?
3) No odd shading artifacts but will keep it in mind if I see any - thanks.

B
