 ### Added
 - Added the ability to downsample to 10K or 2K resolution for freesurfer runs
+- Added the ability to run AFNI 3dDespike on template-space BOLD data.
 - Added the ability to ingress TotalReadoutTime from epi field map meta-data from the JSON sidecars.
 - Added the ability to use TotalReadoutTime of epi field maps in the calculation of FSL topup distortion correction.
 - Difference method (``-``) for ``CPAC.utils.configuration.Configuration`` instances
