Actually, if you have a Mac, you can try our our SAC DHI module,
which would allow you to get response information via CORBA:

Sorry, I forgot about that one.

Greetings,
I am trying to deconvolve the instrument response but need poles and zeros
files corresponding to them. Does anyone know where I could get them from?
Thank you.

Hi all,
I can open matlab from any window. I am trying to use matlab from sac, but I can not link to it. The set of the current directory for matlab is ok, but after that the ERROR 8002 appears again. Also "mat file.m" does not work. I am using Suse. Could help me?

Has anyone ever had a problem with merging a lot of data. I have 5 days
of data recorded at 250 Hz. The files were acquired and saved in 30
minute intervals. I am now trying to merge all the half hour sections
into one file. The merge function seems to work fine until I get to the
3rd day, but after that the data starts to look corrupted and gets
choppy. It kind of looks like the trace has been down-sampled.
If I look at the individual traces before merging the data look fine. I

64-bit static .a library.
even i used :
./configure --prefix=mypath CFLAGS=-m64 LDFLAGS=-m64
how come it's still 32-bit library?
here is an output of the 'configure'

Re: x64 compilation problem - Brian Savage - 2008-02-15 18:49:22
Yang, Ting
Dear all,
I was trying to install the latest SAC v101.1 on my 64 bit Ubuntu
system. I got the following error:
-----------------------
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run C
compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
-------------------------
I have the the newest version of gcc.
Anyone has the same problem or knows the solution?
Thanks a lot!

The above macro works in sac 100.0 but in 101.0
the first setbb statement causes error 1201

Typically YYYYMMDD will be something like

Dear Users and Programmers of SAC,
i am using several years the Sac code and i think the new version
is the best we ever had with one exception:
The precompliled linux binaries never worked for two 32bit computers
with Suse Linux 10.1. I had to compile the source files to make it
work!! Thanks

In the announcement for sac version 101.1, it was stated that one could
build sac for Cygwin (Windows) from the same source distribution as used
for the other operating systems. As explained below, that is not correct
and a separate source distribution for Cygwin is required.
Modifications for version 101.1 to some subroutines used in the sacio
library led to problems with Fortran programs run on the Mac PPC. These
problems have been corrected in the source and binary distributions.

Hello,
I need to write my own stand-alone codes in FORTRAN and use SAC2000
library routines to handle I/O of SAC formated data files. The library is
called sac.a, and it says that it is available on the SAC ftp site.
What is the ftp site link (URL)? I cannot find it anywhere and the
available external links are broken. I need that library for Linux x86.
I would appreciate any help.
Regards,
Igor

Hi Dylan,
Below's a simple shell (csh) script to automatically extract header
information from multiple sac files. You have to only change the name of
your input files, and should be able to run it, I added some comments,
hopefully they will help get you on the right track. Good luck, Eva

# This is the list of your sac files, with some kind of identifier

Hi All,
Is there any way to write a blackboard variable and/or a particular
header value (such as user0) to an ascii text file from within SAC?
I can't find anything close to this other than writebbf. I also want
header values so I need something else.
Thanks,
Dylan
