[SAC-HELP] PPK alignment

[Jonathan MacCarthy]

Hello, SAC users.  I could use some advice about how to line up a group of 
traces while assigning picks.  I've got 10 similar traces and I want to line 
them up on prelimary P picks so I can correct the bad ones, but "ppk rel p 10" 
lines traces up on "o".  I can't find a way to change this or rewindow the data 
without destroying the files' "o" times.  Does anyone know of a workaround?

Thanks for your help!

Best,
Jonathan
