ECAT correction for one sample t-test

I guess it went lost on Xmas time (But the wishes are still valid :-))

Hi there (and merry Xmas ofc),
I’d like to run 3dttest++ one sample with covariates (a-la 3dregana mode).
Can I use ECAT to control for FPR?
If yes how? what I though is run ttest one sample without covariate AND with covariate and subtract the two masks. The voxels which are in the mask without covariates and not anymore in the mask with covariates are those that depend form covariate. Is this approach correct?
If not should I rather prefer clustsim approach?
Cheers,
Claudio
