Hi Rodrigo,
Before giving an interpretation we need to see the design and the contrasts.
All the best,
Anderson

Hi,
I am trying to apply randomise in a 4D sample using the following command:
randomise -i $FILE -o rand_${FILE//.nii.gz} -d design_Lcline.mat -t design_Lcline.con -n 5000 --T2 -D
I performed these in different metrics (e.g. FA, RD, AxD, etc) and I have 40 nonzero voxels in the same XYZ locations but when I look at the output of *corrp_tstat1/2.nii.gz output the number of voxels decrease (but not in the *tstat1/2*.ni.gz output). So... my questions/concerns:
1). Could somebody give me a intuitive information on why/how is this happening? I'm about to read the TFCE paper but some discussion on this issue will be greatly appreciate it.
2) These voxels are along a specific tract and perpendicular (or along) voxels are not included so I was wondering if the --T2 option (and/or some other options can be recommended).
Thanks in advance,
Rodrigo
