Hi,
Using SAC, I am trying to apply time-shift on a signal by adding zeros in the beginning of a time series.
I use
Cuterr fillz; cut b 20
To implement 20 sec time shift in the beginning. But nothing happens.
What is the correct format of the command. What other options I have to apply a time-shift?
Regards,
Zoya Zarifi

The help file is confusing and a rewritten version will be in v102.a. But to see how to do what you want, run the attached macro: cut.m spelled out below
echo on
cut off
fg seismo
rtr ; taper
lh b e a npts kztime
write seismo.sac
cuterr fillz ; cut b -5 e
read seismo.sac
lh b e a npts kztime
title "fg seismo; rtr; taper; write seismo.sac ; cuterr fillz ; cut b -5 e; read seismo.sac”
p1
To run it,
