Re: Poles and Zeros from Guralp

Gonzalo:


I would not mess with this in this way.

Use PDCC to make a dataless seed volume for your Guralp sensor.

Then convert the dataless to RESP using rdseed (./rdseed -R -f <dataless>)

Now place the RESP files at CAL/

Poles and Zeros from Guralp

gonzalo antonio fernandez marañon — 2013-05-17T15:47:08

Dear Community.
Again me. Maybe now This question will be so silly for you.
I am trying to get the poles and zeros from a Guralp to Seissan fomat.
I was reading the manual for getting the response file until I get
"stop" at this point.

Guralp Poles and Zeros:

-23.56 x 10-3 ±j -23.56 x 10-3   0
-62.3816 ±j 135.392                   0
-350
-75

Then my NOrmalizing factor is:
5,763 X 10^16

I assume that I must Multiple the Normalizing Factor with the poles
and Zeros like this:

(-23.56 x 10-3 ) X (5,763 X 10^16) = -1357X10^14

(j +23.56 x 10-3) X (5,763 X 10^16)= 1357X10^14

IS it ok
Best Regards.

mulplt cont shift in time

Grazyna Holeczek — 2013-05-15T20:25:51

Hello
I store data in some continuous databases. One database keep data from one 3D station.
It is very useful to see all traces in one window synchronized in time through the command mulplt-cont-start time-interval..... Unfortunately sometimes happens that data from one station are shifted one second back in time and time differences between stations are incorrect. What is wrong?

Best regards

Seissan Issues

gonzalo antonio fernandez marañon — 2013-05-11T20:36:15

Dear Community Hope all of you areso well.

Well my concern is about Seissan, I got a waveform from a Sixaola SP
sensor, well the sensor is under tests, it is installed in the 1st floor
inside a box and tighten to a concrete surface, somehow a spike appears in
the E-O channel and Seissan attenuates all the signal, I know it is a silly
question but Do you know why does Seissan do it? (attenuate the signal when
a spike arrives).
best Regard.
Gonzalo
PD: The Z channel is attenuated.

Re: IASP phases are not displayed

2013-05-10T07:42:00

Jens,

It isn't a reason, all generated times are within the time window.

I think it could be a problem of Seisan version or configuration.
From which version of Seisan is it possible and what procedure allows the time displaing (what procedure should be changed to new one)?

one resason could be that the times generated do not correspond to the 
waveform time window you have, mayne you have a wrong hypocenter or origin 
time. check the iasp.out to see if times correspond.

Wood Anderson follow up: problem removing instrumentresponse

Hello all,

I have the same problem as Carolin Boese (email below) from 28/8/12.  I was
wondering if this problem had an answer as I have been unable to find an
answer, or a solution myself.

I have generated response files in GSE format (PAZ) using the seisan RESP
tool (see below), and on applying the Wood Anderson transform in mulplt
I receive no error message, but see the same amplitudes as Carolin does

Re: Plotting continuos

Branden Christensen — 2013-05-04T02:48:44

Edwar:


Buenas noches.

Seisan appears to have a limit on how much data it can store in memory. 500
sps is a LOT! Here are some possibilities:

1. Convert the data to miniseed and use mscut. I always find miniseed much
easier to deal with. There are a lot of miniseed management tools out
there.

2. You can use either "wavetool" to split the files or "seisei" which
allows you to merge and split waveforms. Seisei works for seisan or
miniseed formats as input/ output. But I have never tried so many samples
with these programs, so they might also throw the "Too many samples" error.

3. Reconfigure the digitizer to output smaller, seisan friendly files.

4. Put all the data into a SeisComP Data Structure (SDS) and then cut it
out by time window using mulplt (this requires a more or less up-to-date
Seisan version). If the data is already in SDS and you are using SeisComP,
then you can use scart too.

If this is a one time problem, then you need a quick fix.

If this is a long-term or routine problem, then we need

Plotting continuos

Edwar Alberto Zambrano Martinez — 2013-05-02T15:28:19

Hi Seisan Community,

I have continuous data in GCF format and I tried to plot in seisan but i
have not gotten good answer.

The procedure that i did is the following:

Procedure A

   1. I convert continuos data from GCF to SAC with the gcf2sac routine
   2. I convert continuos data from SAC to SEISAN  with Wavetool routine
   3. I make a database with MAKEREA routine
   4. I register the continuos data with the AUTOREG routine
   5. I try to plot the continuos data with the MULPLT routine but this is
   not possible (see Figure)

[image: Inline image 2]

The continous data time is 1 hour with rate sample of 500 samples per
second.

Do you know other procedure to do this faster?

How many samples support SEISAN to plot continuos data?

How to split continuos data to plot it?

Could you help me how to plot this information?

I appreciate your cooperation and assistance

Thanks

Re: ascii data in physical units to Seisan

Lars Ottemoller — 2013-05-02T14:16:26

Hi Grazyna,

you will need response files, but if your units are displacement this  
may just be a scaling factor. Note that response files in SEISAN are  
displacement response files.

Lars

Hi Eduardo

I have tried to work with SAC velocity file in Seisan already but when I try to make groung motion or Wood Anderson I get comment "no response info" and nothing is changed.
What is your experience, can you make Wood Anderson (displacement seismogram) with SAC velocity file without response file?
If everything works fine by you, could you please send me SAC velocity file example (best the SAC ascii file)? I use Seisan for Windows.

Thanks for your help, greetings

If you have a huge database, may be it's better to use seisan for

I had the data already triggered, I worked directly with my data in SAC.

Hi Seisan community

I have got ascii data in physical units, some channels of velocity in m/s and some other acceleration in m/s2.
I know the comment ASCSEI converts ascii data to seisan but I see Seisan usually works with data in counts and response files. Is it the only way?
Is it possible to input direct data in physical units without system response and process it in Seisan?

Incompatibility with Windows 7 64-bit?

Edouard K — 2013-05-01T15:37:15

Good day,

I have tried to run Seisan version 9.1_windows on Windows 7 64-bit. The
program installs, but the overhead of the windowed screen of the Seisan
program displays “Seisan 8.0”. Alas, Seisan also tends to freeze due to
almost any operations making it impossible to work with.

I presume that Seisan is only compatible with any Windows OS of 32-bit, as
mentioned in the read me file of Seisan version 9.1, and that the problem
does not lie with me.

With best regards,

Edouard

Dear Alberto Martinez,

Please find in attachment an example of a gursei.def file that I'm using. You should modify according to your own codes and stream id. 36287 is the System ID and BRBL is the Stream ID  (given by Scream!).

It should be in DAT (or wor) directory.
