These failures are from the AFNI_data6/group_results directory? Exactly what command did you run?
This command seems to work, for example (as does simply adding -ETAC):
3dttest++ -prefix stat.5.ETAC.o64 \
-mask mask+tlrc \
-AminusB \
-setA Vrel \
FP "OLSQ.FP.betas+tlrc.HEAD[Vrel#0_Coef]" \

-ETAC_opt NN=2:sid=1:hpow=0:name=E.MB:pthr=0.01/0.001/10:fpr=5
Is that failing for you?
I have kept -paired, since that shows more of an effect.
