Hi Linda,
Add subject (and group) labels, which is a good idea
anyway, e.g.
3dttest++ -setA GROUP_1 \
subj1 /subject1/1.niml.dset \
subj2 /subject2/1.niml.dset \
...
-setB GROUP_2 \
subj3 /subject3/1.niml.dset \
...
If your groups are in separate directories, which is
also a good idea, use gen_group_command.py to
quickly generate a 3dttest++ command, e.g.
gen_group_command.py -command 3dttest++ \
-dsets GROUP1/subject*/1.niml.dset \
-dsets GROUP2/subject*/1.niml.dset
See the -help output for examples.
