Dear AFNI experts,
I have a question regarding 3dttest++.
I have run a 3dttest++ with the below script.
3dttest++ -paired
-clustsim -prefix 3dttest++_Ex-Rest
-mask sub26/sub26.Condition2/results/mask_group+tlrc
sub101 ‘stats.sub101.Condition1+tlrc.BRIK[10]’

sub117 ‘stats.sub117.Condition2+tlrc.BRIK[10]’
sub118 ‘stats.sub118.Condition2+tlrc.BRIK[10]’
sub120 ‘stats.sub120.Condition2+tlrc.BRIK[10]’
sub121 ‘stats.sub121.Condition2+tlrc.BRIK[10]’
sub122 ‘stats.sub122.Condition2+tlrc.BRIK[10]’

sub138 ‘stats.sub138.Condition2+tlrc.BRIK[10]’
sub139 ‘stats.sub139.Condition2+tlrc.BRIK[10]’ \
And, this resulted in the below sub-bricks
sub-brick #0 Condition 1 - Condition 2 mean
sub-brick #1 Condition 1 - Condition 2 Tstat
sub-brick #2 Condition 1 mean
sub-brick #3 Condition 1 Tstat
sub-brick #4 Condition 2 mean
sub-brick #3 Condition 2 Tstat
When I ran the above script using stat files from the different simuli and it resulted in the below results.
sub-brik #0 Condition 1 - Condition 2 mean
sub-brik #1 Condition 1 - Condition 2 Zscr
sub-brik #2 Condition 1 mean
sub-brik #3 Condition 1 Zscr
sub-brik #4 Condition 2 mean
sub-brik #3 Condition 2 Zscr
I am wondering why these resulted in different sub-bricks and if Zscr generates different result from Tstat.
Thank you in advance,
Junyeon
