Dear Afni experts,

I am trying to run a group analysis using 3dANOVA2. I am looking at two conditions B and C and want to see the main effect of each across two subjects. Each individual's data looks fine, and has appropriate motor strip activations, however, the mean activations for each condition (given by -amean 1 and 2 respectively) show no significant activations.

In addition, the tailairached activations fit the talairached anatomy fine before the ANOVA, but seem shifted (posterior and inferior) following the anova.

Below is my code for this ANOVA:

3dANOVA2 -type 3 -alevels 2 -blevels 2 -dset 1 1 B_AB_bf_irf_mean2+tlrc -dset 2 1 C_AB_bf_irf_mean2+tlrc -dset 1 2 B_BT_bf_irf_mean2+tlrc -dset 2 2 C_BT_bf_irf_mean2+tlrc -amean 1 B -amean 2 C -acontr -1 1 BvC -fa stimEffect -bucket ANOVA_2

Let me know if you need me to attach the data.

Thanks
Sarah
