Thanks, that can explain the smoothed look of the time series in the middle slices.

I did:

$ 3dinfo -orient pb01.rest1_14.r01.despike+orig.
RPI

This indicates that the Z-coordinate (or k) goes from low/neg to high/pos when travelling up the stack. Which is what i see in the viewer as well. Attaching print screen of the despike time series (top) and the tshift time series (bottom) of the most top slice. Code from the .proc:

# ================================= tshift =================================
# time shift data so all slice timing is the same 
foreach run ( $runs )
    3dTshift -tzero 0 -quintic -prefix pb02.$subj.r$run.tshift \
             -tpattern seq+z                                   \
             pb01.$subj.r$run.despike+orig
end

# --------------------------------
# extract volreg registration base
3dbucket -prefix vr_base_min_outlier                           \
    pb02.$subj.r$minoutrun.tshift+orig"[$minouttr]"

Something is not right, right? The peaks travel to the right.
