Despiking in AFNI -> summary

Dear AFNI experts,

I have been asked to report despiking statistics (number of volumes / voxels despiked in each subject). For what I can see, this information was not “saved” anywhere with the standard 3dDespiking procedure - implemented using afni_proc.py.

So there are my questions:

  • how can I keep track how how many spikes are corrected in voxels?
  • how much do you think that the number of despiked spikes would affect the autocorrelation across the brain?

Thanks in advance,

Simone
