As promised, we've now released a new script and instructions for
running TBSS on DTI-derived data other than FA. It is still necessary
to run a complete analysis on FA data first, and then other data such
as tensor eigenvalues or MD can also be projected onto the mean FA
skeleton.
The new instructions are at:

The updated script can be found at:

(or you can just re-download FSL from scratch).
Cheers, Steve.
