Dear FSL Experts,
How group analysis & statistics can be done from >1 subject's classification results (seeds_to_*). & normal one seed (fdt_paths.nii) results from multiple subjects.
1)
#individual
>find_the_biggest seeds_to_*.* biggest.nii
>mri_binarize --i biggest.nii --match 1 --o s1_1.nii
#group
>fslmaths 1_biggest_subject01.nii -add 1_biggest_subject02.nii -div 2 1_biggest_avg.nii
or
Should I first sum all the seeds_to_* with same identity, and then run |find_the_biggest| for group. or Should I run find_the biggest for individual and group these results by adding them.
2)
calculation of number of streamlines & connectivity
value, should it be done on individual subject for all seeds_to_* , and
then calculate a mean for group ?
3) one seed tracking results group track generation:
>fslmaths fdt_path_subject_001.nii -add fdt_path_subject002.nii -div 2 avg_track.nii
Is this fine ?
Thank you
