AFNI program for randomly shuffling time series data?

Hi AFNI gurus,

Is there an AFNI program for randomly reshuffling time series data, independently for each voxel? I’d like to use this to estimate the null distribution for the correlation between a seed region and other voxels in the brain (i.e. functional connectivity) in one of my datasets. Alternatively, is there a program that can help me estimate such a null distribution?
