Hi,
what artifacts are you talking about? If I understood correctly, you have imaged a vitamin marker attached to the brain? Why is this causing artifacts? Can you show them in a figure?
Unless you want to include crossing fibre information (that also depends on whether the data you have are good enough), you do not need to run bedpostx for TBSS.
Cheers,
Stam
