Hello,
I have two questions:
1. VBM (preliminary) question:
I followed the VBM instructions in the FSL-VBM
practical posted on internet under
www.fmrib.ox.ac.uk/fslcourse/lectures/practicals and,
after running the last permutation step, I was hoping I
could view some statistically signifficant clusters and
their significance but I do not get the image
grot_maxc_tstat1, only grot_tstat1 and
grot_clustere_corrp_tstat1. Is any of these two
products to be used instead of the file mentioned on
internet? Also, how do you tell significance from these
images? (or is it hidden in the parameters passed to
randomise or elesewhere?)
2. VBD (main) question:
If I want to do a similar analysis for the FA/MD files
obtained from DTI scans, should I follow the steps
performed in the VBM analysis scripts
(fslvbm_1/2/3_bet/template/proc) with minor adjustments
or start on a different track? Are there instructions
somewhere about how to do such an analysis?
Thank you,
