Good evening sir.I am Bijayananda Dalai from India,currently works as ph.d
research scholar at CSIR-National Geophysical research institute,Hyderabad
.I have a very small query regarding sac data
manipulations(cutting).However, my raw data sets are of sac format that
consists of day file(one raw sac file/day/station) and i donot know more
about sac files in which portion of the waveform the earthquake is
recorded. i just want to apply receiver functions on my raw data sets.For
this, data need...

Hello everyone,
Probably a very simple question. I already install sac for mac (El
Capitan), and almost everything is working fine. However, I cannot use the
"ls" command (for example to use a list as input in setrfslow or hk)
SAC> ls
ERROR 1106: Not a valid SAC command.
There is some way to fix this problem?
Regards,
Claudia

Hello,
I've installed the SAC package and I can plot stuff, but the 'make check'
command throws out a pytest.sh error along with quite a few undefined
header warnings. I've included the output in a text file since it's quite
long. Thanks for the help.

Hi All!
When installing SAC v101.6 (on a 2018 MacBook Pro, running “High Sierra 10.13.6), I am successful able to run:
% mkdir build
% cd build
% ../sac-101.6a/configure --prefix=/usr/local/sac > ../130612.build
% make >> ../130612.build
But running:
% make install >> ../130612.build
generates the following nasty looking errors::
/usr/include/secure/_common.h:39:53: note: expanded from macro '__darwin_obsz'
#define __darwin_obsz(object) __builtin_object_size (object, _USE_FORTIFY_LEVEL >...

Hello everyone,
I am trying to use a MACRO for data processing that is available in the
Charles Ammon's webpage.
The entire code is working quite well, but for some reason that I can not
understand the code is not capable to read the files continuously. When I
try to process a lot of data, I just can process the vertical component
continuously but the files for the N and E components don't change. So, at
the end, I just finish processing vertical seismograms, which is not that I
need to do :...

Dear Susan,
In my previous email, I gave the 1000sps output of a seismometer. I have also 200sps output from the seismometer. So, There are two observed data set with 200 and 1000sps at the same time.
the seismogram after decimation 5 with FILTER OFF option is similar with the 200sps output of the seismometer.
Actually I cannot realize my problem with sine example.
However, I generate seismogram with FUNCGEN. I see the aliasing on the P-phase after "decimation 5 FILTER ON" command. Small ...

Dear all,
I have 1000sps data. When I apply decimation (#5) with option FILTER ON, I see strange waveform. However, FILTER OFF option gives much appropriate waveform.
I am confused with FILTER option.
best regards
