Cross autocorrelation

I’m interested in assessing directions of functional connectivity of a 3d+time dataset and a 1D ideal time series in resting state data. For example, 3dfim++ can be used obtain the lag(0) correlations with an ideal file of 200 time points and a 3d+time dataset of 200 subbricks.

Does AFNI offer a tool for obtaining something like 3dfim++ except with cross-correlations obtained at a specified lag?

Thank you.

One possibility is to manually shift your 1D ideal time series with a specific lag and then feed it to 3dfim++ or 3dDeconvolve.
