[Mrtrix-discussion] display peaks vector in FSL

[J-Donald Tournier]

Hi Yonghui,

There may be different reasons for this. Can you be more specific as to
exactly what the problem is? Does FSL display the wrong directions, or does
it fail to display anything at all? Are the directions somehow rotated or
flipped when viewed in FSL? Some screenshots would also help.

Thanks,
Donald.
