In the command tckgen, what’s the difference between -seed_gmwmi and -seed_dynamic? Now I have a HCP data, which one should I use? I have run them and calculated fiber lengths, as follows
tckgen WM_FODs.mif 1M.tck -act 5TT.mif -backtrack -crop_at_gmwmi -seed_dynamic WM_FODs.mif -maxlength 125 -select 1M -cutoff 0.06
tckgen WM_FODs.mif 1M_gmwmi.tck -act 5TT.mif -backtrack -crop_at_gmwmi -seed_gmwmi gmwmi.mif -maxlength 125 -select 1M -cutoff 0.06
Any suggestions there?
