Robyn,
What about using snpm (holmes + nichols)?

the Gaussian random field corrections require assumptions regarding the
smoothnes of the residuals, which would certainly not be true for
unsmoothed trace or FA images, and I doubt that you want to smooth
these images. It may be possible to use the false discovery rate
correction, but I'm not sure whether the non-normality of the FA images
would be a problem (perhaps Tom Nichols can chime in on this?).
cheers
