Hi everybody!
To correct the header of my waveforms (for example entering hypocenter information to sac header), I use this script:
#!/bin/csh
set outdir=/home/sonia/Slip/sacheader
set origin=(2012 01 11 17 08 00.79)
set lat_lon_dp=(36.3533 52.7873 15.6)
# --> year mm dd hh mm ss.s
# --> 2003 04 29 13 53 16.8
set evla=$lat_lon_dp[1]
set evlo=$lat_lon_dp[2]
set evdp=$lat_lon_dp[3]
set jul_day=`julday $origin[2] $origin[3] $origin[1] | grep Julian | awk '{pri...

Hello,
I am attempting to merge several sac files into single day segments. My
commands are working if there is a gap in the data (fills in with 0s) but
if there is an overlap I get, for example, this error:
SAC> r GS.OK030.00.HHZ.D.2015.327.000000.SAC
SAC> merge GS.OK030.00.HHZ.D.2015.327.062124.SAC
ERROR 1802: Time overlap: GS.OK030.00.HHZ.D.2015.327.000000.SAC
GS.OK030.00.HHZ.D.2015.327.062124.SAC

Dear all,
I downloaded 10 days continuous waveform data in seed format from BREQ_FAST
Request. And try to convert it into SAC format. I applied rdseed -df
(seed file name) command and got the following error. However, for one-day
data, I had no error. In this regards, Could you please give me some
suggestions?
Thank you in advance!
My error is:
Writing XQ.NA010..HH2, 19999039 samples (binary), starting 2015,229
03:46:38.6700 UT
WARNING (process_data): too much data (burp!).

Hi there,
I'm downloading SAC onto my laptop, which runs on Mac OS 10.12.6. In the
README document I see that it says SAC will run on earlier versions of Mac
OS X, e.g. 10.7, 10.8, and 10.9. It also says that "Other platforms or
operating systems must be built from the source code." Does this mean that
with my newer operating system, I will need to build from the source code?
And what does that entail?
Thank you,
Mel Zhang

Hello,
I am curious if it's possible to color the grid differently from the
skeleton.
Basically, to have a plot where the waveforms are red, the
letters/numbers/frame are black, and the grid lines are gray (or blue)?
Thanks,
Igor
