Hello
Does somenoe know how to define a page orientation in sac
in order to have portrait instead of landscape?
I know that I can define a size using xvport and also SGF.
Can I do it differently?
Best regards

Hi
Running 'unwrap' both on solaris and mac os x I get the following error: "remove this function: src/co/zmemad()". What does this mean? Is this a bug?
Cheers -John

Hi all
I have a simple question. While using rsac1 which is for evenly spaced
file, what does evenly spaced means ??? is it evenly spaced sample
data or what?
another question is i am making some changes in header like the time
of the origin of an event and using wsac0 but after that for some
data (not all) it is saying that "data not evenly spaced" when am
again using the rsac1 cmd.
do i need to use : CALL SETLHV ('LEVEN', .TRUE.,NERR) to counter this problem?

Hi,
I used READTABLE function as follows but have been getting ERROR 1301: No data files read in.
READTABLE CONTENT P. file_a.txt
Also, I tried XN . in the place of P. without any luck.
file_a.txt (in the same directory) looks like this with column 1 being time and column 2 being amplitude,
1.23E+003 1.40E-010
1.23E+003 1.10E-010
1.23E+003 8.18E-011
1.23E+003 5.43E-011
1.23E+003 2.80E-011
1.23E+003 3.23E-012
READTABLE should be a simple operation (right?). Could someone please …

Hello everyone,
I have a time series of synthetic traces and would like to convert them to
SAC format. I know I could use the CONVERT function but before that I have
to format the ASCII (time series) file by arranging the values for sac
header. Is there a utility to do this pre-formatting before I could use the
CONVERT function?
ex. I believe my ASCII file should look like the following before using
CONVERT
0.125 -7441.313 4087.937 1 -12345
-12.734…

Hi Stuart,
SAC is now a community developed and supported program, the best place
to find help is the sac-help mailing list (CC'd), list info is here: http://www.iris.washington.edu/mailman/listinfo/sac-help

What you describe smells like an endian issue, search through the
email archive I found this message:

Using sac 101.2 I was able to successfully read back data written on
my little-endian Mac by changing…

Hi SAC users,
I am having some issues with timing...please see my steps below and I
have attached the miniseed file in case anyone wants to try this
themselves. I am losing millisecond information when I use the command
ms2sac to convert data. I wonder if anyone has seen this before and how
to fix it?
Thanks,
Dylan Mikesell
