Dear Sir, I have RESP file and polezero file which produced from SEED volumes by the RDSEED program. I want to remove the instrument response from "file.SAC" and apply the the polezero file that I create. if I apply the command "trans from evalresp to polezero subtype "created filename" freq 0.025 0.05 10 20" is it correct command and makes sense? Should I do a taper command when I apply transfer? If I don't do it, what's the effect on my signal? Thank You Regards, Ami

Hello, I am using SAC version 101.6a on Mac osX 10.9.5, and I am running ppk to pick p waves for several stations at a time. I type ppk p 4 to view four stations at a time, but I can only zoom properly in the first subwindow (at the top of the first four traces plotted). As I scroll through all of the stations to pick them, when I try to zoom, the zoom function zooms in on the wrong portion of the trace. Has anyone else had this problem, and does anyone have any advice? Thank you very much!

Dear Sir/Ms How do I determine the freqlimits f1 f2 f3 f4? should I see the spectrum of the origin signal first or I can determine it randomly as long as f1 < f2 < f3 < f4? Thank You Regards Ami

I'm trying to use the "grayscale" function with volcano.xyz or others 3D files but I receive the following message: sacrunfile: 1: sacrunfile: Utahgrayscale: not found I installed the urt-3.1b but I have the same problem. Do you have any recommendations about how to solve it? All the best. O'Leary
