I would expect the autocorrelation to be highly inflated by any termporal interpolation.

Assuming this is task data, performing a regression with 3dREMLfit should account for an ARMA(1,1) noise model, rather than using a simple least squares fit method, as would be done by 3dDeconvolve or 3dTproject.
Presumably this is not rest data.
