Hi Lukas,
Your cases 1 and 2 are identical. Case 3 is not related.
As a test, I ran the following commands (working with
real-time generated dastaset rt.#001+orig):
case 1:
3dTshift -ignore 3 -prefix tshift rt.#001+orig.
3dvolreg -base 3 -prefix tsh.i3.vr.b3 tshift+orig.
case 2:
3dvolreg -tshift 3 -base 3 -prefix vr.b3 rt.#001+orig.
Next, to compare the results, the datasets were subtracted:
3dcalc -a tsh.i3.vr.b3+orig. -b vr.b3+orig. -expr a-b -prefix diff
** the resulting diff+orig time series was all zeros
As for case 3, using "3dDeconvolve -tshift" only corrects
the OUTPUT time series (from the '-iresp' option). It has
no affect on the input data.
I hope this helps.
