I want to test the basic algorithms of another program that
reads only CSS-format data from arrays. Hence I generated
a set of impulses in SAC and tried to write them to a CSS-format
file with "writecss".
This failed with ERROR 1385: No worksets in memory.
The traces look OK with "p1", which I assume means that they
are "in memory".
I tried to write the same set of impulses into an IMS (GSE)
file with "writegse" (because I could convert this format to CSS
with another program) but this cra…

Hi,
I couldn't find in the Users Manual how to parse SAC ASCII files (write
alpha).
I see 30 header lines and 3 tail lines. In between I see 5 columns.
Can anyone help me or point me to the right page in the manual?
Thanks,
Shahar

Hi,
I would like to read multiple SAC files into memory using a file which
contains the SAC file names.
According to the SAC book, I can do:
systemcommand to list cat list_file
while read list filename
read filename
enddo
However, I get the error:
"sh: to: command not found"
Why isn't this working?
According to the online command index there's no "to" syntax for
systemcommand:
http://ds.iris.edu/files/sac-manual/commands/systemcommand.html
Is there a different way to do this?
Thanks,
Sh…

Silvana,
Checking old e-mails of the sac-help, i find an e-mail from Brian Savage (Set,15 2009)
where him suggest the update of sac software to avoid the X problem.
Cheers,
Milton

Hola Silvana,
The problem seems your video card, the error :
X Error of failed request: BadMatch (invalid parameter attributes)
googling it to see a possible solution.
Can you plot the trace only? to check that X system works.
i assume you running on sac on Linux.
Is true i use OS X 64 bits and sac 101.6a (last version).
HTH,
Milton

Hey!
I am having a problem installing SAC on my mac (OS X Yosemite 10.10). I have tried to run the script (./sacinit.sh) on bash, don’t observe any action… and then tried to check if sac has been installed somehow, however a message shows up "bash: /usr/local/bin/sac: Bad CPU type in executable”..
I am right thinking it is because of the version of my OS? since sac is only possibly valid for upto OS10.9?
*would really like away to be able to install sac with on my mac?
Appreciate any help…
