Hi Rick,
Changing the header information with 3drefit worked, but i still have problems with the cluster explorer. Regarding to the z-scores, I did use -Clustsim and -ETAC options in 3dtest++. When I convert those z-scores into t-stats with 3dcalc and then change the header, the Cluster explorer behavior the the same one as if as use a 3dtest++ input without -clustsim and -ETAC options. That is great! but I still have error messages like this:
Attaching package: ‘afex’ The following object is masked from ‘package:lme4’: lmer
Error in factor(mean.df$Group, levels = c(lab.a, lab.b), ordered = TRUE) : objeto 'lab.a' no encontrado
Calls: <Anonymous> ... sourceUTF8 -> eval -> eval -> ..stacktraceon.. -> factor
Thanks a lot,
Karel
