> Gang: can I use a dataset as covariate in 3dttest++?

Yes. Read the 3dttest++ help for the usage and details.

I don't know the context of your analysis. However, it's generally not considered a good idea to perform analysis on statistics including t-stats. Instead, it makes more sense to make inference on effect estimates such as beta values.
