Dear all,
I'm using the SSS SAC subprocess to stack files. The files I stack have
the same header, because they
are obtained by noise cross-correlation between stations pairs.
Therefore, I would like to keep
the entire header in the sum file. Is that possible to use a simple SAC
command to do it,
without passing trough macros that I can write myself.
Thanks
Maria Silveira

The details of a specific response file (Station, Network, Channel, Location
code and time period) would be helpful.
I think that SAC uses evalresp code that may not have been updated in
some years. I don't know if a more recent evalresp source code could
be substituted or if its no longer being maintained now the jevalresp
is being maintained.
As the Seed RESP file format evolves, evalresp needs to be updated
and added to SAC to keep it functional.

Hi,
I'm trying to use 'evalresp' on some data with a transfer function coefficient
of type B in the 'Response (Coefficients)'.
When I try to do so I get an error message of the following form:
EVRESP ERROR ()
parse_coeff; parsing(FIR_ASYM), unexpected filter type('B'),
skipping to next response now
The output file that results gives a blank trace.
I have found, just through messing about with it, that changing the 'B' to a 'D'
in the RESP file removes the error message, and giv…

Hello all:
I just joined the list, but have been a SAC user for a long time.
I have installed SAC2000 and use it along with my Fortran programs to do
several tasks. The problem is that I am worry SAC2000 will only work in
32bit machines and my lab will soon migrate to 64bit ones. Is there a
binary for the 64bit computers which I could get right now?
I asked the author of SAC about that and he asked me to post this
question in this forum. Hope you can help me.

Hi
i have used SYNCH command(then writing the header with WH command or W OVER) before cutting the data file and then do FFT AMPH and writing the Amplitude file then perform some operation on 2 Amplitude file. and then i wanna add 2 files togother and taking the SQRT and Saving the file again. but, actually in the Midd of my operation(while i'm adding the 2 file togother) I DO have the same error messege for header mismatch..!!
DOES ANY ONE KNOWS WHY IS THAT..?
EVEN MY ORIG…

Does anyone know if SAC (release 100) works on Intel Macs?
Thanks,

Dear sir
try to synchronize the data before the fft.
So use
synch and
wh to save the header.

I was trying to extract the SAC file (*.tgz) IRIS sent me and install
SAC on my MacBook Pro. However, two ways to extract files they suggest
in the email didn't work. Here are the error messages:
