That reminds me: if I mistype a "read" command such that no data is read
into SAC, it then crashes (Segmentation Fault) at the next command. Can this
be fixed? (This is in a Linux version.)

Together with the little program below (which was take from the C
FAQ), we are able to tell the endianness of the sac file! :-)

/*
 * Determine whether an Operating System is big-endian or little endian
 */

#include <stdio.h>

int main()
{
  int x = 1;

  printf("This computer is ");
  if(*(char *)&x == 1)
      printf("little-endian\n");
  else
      printf("big-endian\n");

  return 0;
}

Message-ID: <fd0f51b90809052343k72012585s894a85d9a9a720da@mail.gmail.com>

Dear SAC users and devs,

There is a useful feature in softwares like bash, which can save
command history to a disk file and load it the next time they run. In
this way, people can use hotkeys like Up Arrow, Down Arrow, Alt+P,
Alt+N, etc. to access the commands they've used not only in the
current session but also in the previous sessions. I hope that SAC can
have the same feature so as to make our lives a bit easier.

The feature should not be difficult to implement, and if people
(hopefully both users and devs) think it is desirable, I'll start to
do it. :-)

Hello all,

I was wondering if there is an easy way to save the plots I get in sac? 
Saving an image in png/gif/jpeg would work but I couldn't find such 
options in the sac's help.

Thanks,

Hi Igor,

SAC does not have that capability by itself. It can be done using SAC
and Imagemagick, which provides a tool called convert.

Take a look at this:

If I understand your question correctly, you can save plots you made in SAC to 
an EPS file.

1.  First you must save the plot to a file.  After you get the plot you like, enter

     bd sgf

Then repeat your plot command that had produced your display.  You will not see 
it, but it will produce a file in the directory you are in named f001.sgf.

You can then convert the .sgf file to a Postscript or EPS file using programs 
and scripts provided with SAC.  There is some discussion in utils/README_utils 
(in version 101.2).  There are also comments about how one can make a PDF file, 
if you have the right script.  Making an EPS file requires ghostscript.  Not 
needed to  make a simple postscript file.

To convert the file to JPG, PNG, etc., you need another program.  On a MAC that 
can be done in preview.

Let me know if that is not clear -- or if you had a different question.

Arthur,

You understood my question correctly, thank you.
Your method is similar to the one mentioned by Kuang. We tried it and it 
works!

Thanks again,
Igor

When rotating data to GCP, I get the letter Q in place of either the radial
or transverse headings on the rotated files.   This has occurred on all
files where I rotated the data with SAC 101.2.   I reloaded SAC 101.1, and
there was no problem with any of the files.

When I view the R & T files after rotation, I occasionally notice that
either the R or T file has shifted to the left, and is no longer in vertical
synchronization with the Z, N, & E files.  I have had this happen several
times.  When the shift occurs, it is always to the left, and only involves
one file, either the R or T file.  It has never occurred on both the R & T
files.  I have been unable to isolate a common denominator for this problem.

To whom it may concern

I have modelled a jacket (file attached) and have performed a dynamic analysis on the structure (extract mode shapes). I have fixed the sturcture dynamically on four corners of the jacket and the topsides 222000. At the base of the structure, there is a central joint 2001 (at EL-180) that has spring values applied on them and these values are:
vertical: 7000MN/.
Lateral: 2500MN/m
Rotational: 8E6MN/radian
Torsional: 4E6MN/radian

I analysed the structure with these applied spring stiffeness values and the 4 joints 21,22,23,24 dynamically fixed in all directions (222222) and am getting a period of 44 sec with the structure rotating vigorously.

I need some help with the following:
1. I am unsure how to apply the spring values from joint 2001 to the four corner joint 21,22,23, 24. At the moment, I assume that I will need to rigid link joint 2001 to the four corner joints?
2. If 2 is correct, I am unsure how to rigidly link the joint 2001 with the spring stiffness values to the four corner joints 21, 22, 23 and 24.
3. I am unsure what fixities I need to apply to the four corner joints.

Your help to the above queries would be greatly appreciated. Please help me asap.

Thanks

Subject: [SAC-HELP] FIR normalized
Message-ID: <d884a4ee0809220400l7a1c4b20pb7e3bb7708570ce5@mail.gmail.com>

Dear to all,

When removing the instrument response from the data I get some error
messages that I have not been able to find what are they due to.

These are:
Calper is not available. Cannot tell if response is normalized, so transfer
function will be used without scaling.
Calib is not available. Cannot tell if scale factor has been applied on
input, so transfer function will be used without scaling.
        Waveform multiplied by 1.000000 after deconvolution.

Another error message in some data are:
WARNING: FIR normalized: sum[coef]=9.781101E-01; US AMTX  LHZ


I appreciate if someone could tell me what is it due to, how can I avoid
these errors and, the most important, in what do they affect the
deconvolution.

Thank you in advance.

Hi,

Dear Xuzhang,

Also I have tried to retrieve the header information and some difficulties exits. When you do it from some command window only appears the portion depending the size of the window and if you use a macro occur the same thing. However, usually we need only part of the information, with the following instruction in a cshell script you can save the information that you need, for example if you pick it with A and F markers:

sac<<EOF >! MyHeaderFile
r MysacFile
listhdr AMARKER FMARKER
EOF

I hope that in the next version appear a better solution, specially if some body need all the header.
P.

Message-ID: <5ccd36671641df36ae3e93514eca31ce.squirrel@mail.mcs.vuw.ac.nz>

Hi there,

I am sure this is a known issue but my searches turned up zilch
so, just in case ...

I came to build sac-101.2 on a NetBSD 4.99.58 platform with
gcc (GCC) 4.1.3 20080202 prerelease (NetBSD nb1 20070620), the
sac build being configured thus:

./configure --prefix=/local/scratch/kevin/sac-101.2

resulting in:

Compliation Options for sac (Seismic Analysis Code 101.2)

CFLAGS         =
LDFLAGS        =
LIBS           = -lm -lcurses
Debug          =
Optimization   =
Database       = off
Matlab         = off
X11-buffer     = on
X11-depth      = on
X_LIBS         =  -L/usr/pkg/lib
X_CFLAGS       =  -I/usr/pkg/include
Readline       = off
Editline       = on
Install Base   = /local/scratch/kevin/sac-101.2
System         =  (i386-unknown-netbsdelf4.99.58)


and saw this error:

gcc -DHAVE_CONFIG_H -I. -I. -I../inc        -I/usr/pkg/include -I../inc 
-I../libedit/include -c -o co/zgpmsg.o co/zgpmsg.c
In file included from /usr/pkg/include/readline/chardefs.h:26,
                 from /usr/pkg/include/readline/keymaps.h:36,
                 from /usr/pkg/include/readline/readline.h:38,
                 from co/zgpmsg.c:93:
/usr/include/ctype.h:71: error: expected identifier or '(' before 'int'

/usr/include/ctype.h:72: error: expected identifier or '(' before 'int'
/usr/include/ctype.h:72: error: expected ')' before '?' token

this occurs because the toupper/tolower declarations in this system's
ctype.h

int     tolower(int);
int     toupper(int);

get mangled by the macro declaration in sac's

src/co/stdu.h

#ifndef CYGWIN
/*      macro expansions        */
#define tolower(c)       ((c>='A' && c<='Z') ? (c+('a'-'A')) : c)
#define toupper(c)       ((c>='a' && c<='z') ? (c-('a'-'A')) : c)
#endif /* CYGWIN */

as they are only protected by the CYGWIN define and so appear as:

int ((int>='A' && int<='Z') ? (int+('a'-'A')) : int);
int ((int>='a' && int<='z') ? (int-('a'-'A')) : int);


After removing the macro definitions, the code compiles OK.

Hi Keven,

I've reported the same problem a couple of weeks ago, and provided a patch.

http://www.iris.washington.edu/pipermail/sac-dev/2008-September/000088.html

This should be fixed in the next version.

I knew I wouldn't be the first to have seen this but didn't think it
would be so recent.

I wonder why my search did not throw your post up. I think I must have
assumed it must be NetBSD specific (only recently started using that
platform) so searched with the term NetBSD rather than just BSD.

I don't think I had found sac-dev either ?

Sounds like the inclusion of <ctype.h> is the way to go, rather than
removing the macros for those few systems that don't have the system
calls.

Thanks for the feedback,
Kevin

Dear All,

SAC v. 101.1 either fails or crashes when I try to use "writegse".  SAC v. 100 is OK
