Hi Mehmet,

You must to use the cut command, using in this way:

sac> cut t0 t1
sac> read file
sac> plot
sac> synchronize
sac> plot

In the second plot you see the time windows of cut, the "exact" time
depend of your sampling rate, in other words, if you have 100 s/s
you cant cut for example to=0.00 to t1=10.00, remember that the independent
variable is t in seconds, so your cut resolution is 1/100 of second.
Try cut 0.01 10.00 and cut 0.02 10.00, small values no works.

HTH,

Milton
