Dear AFNI experts,

Hope all of you are staying safe. I am running 3dLME and am wondering how can I analyze Group by Time effects. I have two groups of subjects (A and B) and both groups have before (pre) and after (post) data. Below is the script I used.

3dLME -prefix 3dLME -jobs 5 \
-model 'Group*Time' -ranEff '~1' -SS_type 3 \
-num_glt 5 \
-gltLabel 1 'Apost-Apre' -gltCode 1 'Group : 1*A Time : 1*post -1*pre' \
-gltLabel 2 'Bpost-Bpre' -gltCode 2 'Group : 1*B Time : 1*post -1*pre' \
-gltLabel 3 'Apre-Bpre' -gltCode 3 'Group : 1*A -1*B Time : 1*pre' \
-gltLabel 4 'Apost-Bpost' -gltCode 4 'Group : 1*A -1*B Time : 1*post' \
-gltLabel 5 'Post-Pre' -gltCode 5 'Time : 1*post -1*pre' \
-mask GMmask+tlrc \
-dataTable \
Subj Group Time InputFile \
0001 A pre 0001.pre/clusterave1_r2z+tlrc \
0001 A post 0001.post/clusterave1_r2z+tlrc \
0002 B pre 0002.pre/clusterave1_r2z+tlrc \
0002 B post 0002.post/clusterave1_r2z+tlrc \
.

I could see Group:Time F results in the output data. Could you please let me know if this is the Group by Time effect I am looking for?

Best,
