Has anybody tried getting SAC going on Mac OS X 10.12 Sierra?
I can’t get the X11R6 directory over to /usr which used to do the trick.
Apple has blocked the ability to make any changes to /usr
Thanks,
Steve Taylor

Hi users;
I would like to know if someone could help me in this topic,
I have to deconvolve a sort of files (6 moths of files, file per day) and
I would like to use a macro to read , for example every Z component files
and deconvolve to Acceleration.
(using the response of the z channel that I got previously with rdseed)
There are a simple answer for that or I have to do it one by one,
This is because i have to study the noise of a station in this channel.
thank you for any response, Robe…

Steve,
I was just reading about changes to /usr now being blocked in Mac OS X for another completely different reason today. This may help you.

I am running El Capitan as of last week. I have not yet tried to install SAC. I already had files in /usr/local, so I did not have to do what this web page says. All I had to do was sudo chown to my new UserID. I think …

Dear Sac_help users,
I have some sac data from HYB station located on Indian Shield at Hyderabad. OMARKER doesn't seem to be set at correct value. I requested seed data file and extracted sac data using rdseed using summary file to put the event information in the sac headers.
I am not sure what could be the problem. Any suggestion regarding this?
NPTS = 87180
B = 3.000000e-04
E = 4.358951e+03

Hi Robert,
I have given it a try using the rdseed executable you just send me without
success. To confirm whether its rdseed or the data which has a problem, I
tried two data sets (recent data-2016 and old data-1990).
For the recent data set, i get error message like:-
Output data format will be sac.binary.
INFO: sac variable EVDP will be in KILOMETERS
WARNING (process_data): station/channel AF01/BHZ not found in
station/channel tables for location: .
Skipping this trace.

Hi,
I am having a problem in SAC. Whenever I am trying to use the p1,p2 or
ppk command in SC to plot a seismogram I am getting this error
X11 Screen does not exist
Segmentation fault (core dumped)
and SAC is crashing. I have already installed XQuartz and Matlab is working
fine with the GUI using XQuartz. So kindly help me with this matter so that
I can further process my data.
