Hi there,
I read some old e-mails on the group on paired t-test and
just wanted to check the parameters.
On subject design I choose paired t-test and added
11 pairs, each with the pre and post treatment image. Grand
mean scaling and ANCOVA = yes. Threshold masking = relative,
0.8. Overall grand mean scaling = yes, 50. Normalization =
ANCOVA. The design matrix is attached.
On results I choose the t-contrasts -1 1 and 1 -1.
FWE = 0.05. The first one is below:
The test didn't show any results, so I just wanted
to check if everything is allright with the parameters or
maybe I need a bigger group for some consistent results.
Best regards,
