Voxelwise sliding window time-average in AFNI

Hello folks,

I was wondering if there was an AFNi function that can do a sliding average over several time-steps to have a better rendering in 1dplots ?

I want to avoid big spikes in the time-series data I have.
Because my task in a block design, I would like to have a sliding average rendered.

Does anybody know of any simple way to do this ?

Thanks for any tips.

S.

The program 3dTsmooth (very old) can take as input a 3D+time dataset and output a new dataset where each voxel time series has been smoothed in such a way.
