Hi Gang,
Thank you so much for your advice. It really helps. I have one more question to ask.
I have treated training year as a between-subject variable at first and found that the script did not run. After reading afni's 3dMVM instruction, it seems that between-subject variables are for categorical variables such as sex, genotype or group. So I have added training year as a quantitative variable and the script is running. Could you please check if adding training year as a quantative variable?

-qVars 'Training' \
-wsVars 'Condition' \
-num_glt 1 \
-gltLabel 1 'CondtionA-ConditionB' -gltCode 1 'TST : 1*A Training : 1*A -1*B' \
-mask mask_group+tlrc \
-dataTable \
Subj Training Condition InputFile \
s1 8 A 'stats.s1.A+tlrc.BRIK[10]' \
s1 8 B 'stats.s1.B+tlrc.BRIK[10]'\
s2 20 A 'stats.s2.A+tlrc.BRIK[10]' \
s2 20 B 'stats.s2.B+tlrc.BRIK[10]' \
