Hi all - posted this some days ago but no response. Would like know how to go forward.
This is probably real basic but trying to compare a volumetric structural image of cohort in 2 points in time.
I'm presuming I need to find the differences within each subject between the different time points and then find a commonality between these found differences....to put it in my simplistic way.
Have arranged the sample grouping as follows
pre_1.nii
pre_2.nii
pre_3.nii
etc
post_1.nii
post_2.nii
post_3.nii
etc
I have 17 subjects in all
Have run
fslvbm_1_bet -b
fslvbm_2_template -a
fslvbm_3_proc
Have a series of _struc files in the same order....and no error messages, which is awesome.
Now up to the randomise stage ....and am stuck!
First off am not too sure what my design.mat & design.con should be to get the correct output and secondly presume the design matrix will assign the correct comparison to be made between the subjects. Have looked at various files from the fMRI output but not too sure what is being defined by them.
Many thanks in advance for helping us out here.
Cheers,
Mike
