Dear all,

Please find the attached image.

This is a EdgeTech 3300 HM 5 x 5-array sub-bottom profiler data from Iran
near shore.

I assume  type of reflections are generally caused by gas charged sediments
or poorly sorted sediments. Can anybody give more details on this??

Seisunix management,

I no longer need to be on this distribution so if you could please remove
me, I'd appreciate it.

Thank you,

And maybe try a red-white-black display. The greyscale is hard to see.

How exactly were you trying to remove yourself?

It's a standard mailman mailing list, and every message has special
headers including this:

List-Unsubscribe:
<https://mailman.mines.edu/mailman/options/seisunix>,
        <mailto:seisunix-request at mailman.mines.edu?subject=unsubscribe>

So have you actually tried writing to
seisunix-request at mailman.mines.edu?subject=unsubscribe ? Or using the
web-interface at https://mailman.mines.edu/mailman/options/seisunix ?

IT is strange because the discontinuous reflections are confined to the 
middle layer.? That is if it were gas, then it would have to be produced 
AND confined

to the layer of it source.? Are the units above and below impermeable?

Interpretation is a lot about the context and auxiliary information...

Is this a stacked section? Or a single-channel analog plot?

Message-ID: <CAFCa+2MGOZv86p+7aeKZP11HSFvU2qC_jGJF4PEOToGUNM0HmA@mail.gmail.com>

hi everyone,

I have a problem that I would like to share with you, I need to compare
different seismograms traces from different files, for example, seismogam 3
of the file name1.su and seismogram 7 of the file name2.su, when I use
susum I have one error because  ns are  different. I thought  to convert to
ascii and compare in gnuplot, there it is possible, but the X axis is not
the same that SU, isn't the time values.

- How I can export from *.su to *.ascii with the time colum too? not only
amplitud, I would like to convert many colum that I need.

- It's possible to normalize all amplitudes from different files? if
possible, what is the command?

And the last one,

- How I can plot many traces in one figure with different names? for
example, I plot trace 3 from name1.su, trace 67 from name2.su and trace 5
from name3, and put the name like:  time  vs.  Tr1   Tr2  Tr3   axes.


Thanks a lot for any tips

Hi Jahiro,

suwind should solve (most of) your problems.

You can use it to select traces, and you can use it to select sample
ranges, and even to add zeroes to the end of the shorter file.

Greetings,
Wietze

Subject: [Seisunix] Trouble compiling seg2segy
Message-ID: <CANEsCj5eZvnmzueQo59CyWd7Ycm3PN1D163U3JiLJMJTQnSSBg@mail.gmail.com>

Hi all,
   This isn't exactly an SU question, but seg2segy is among the ThirdParty
codes, and I'm hoping that someone here may be able to provide some
suggestions.

    I'm setting up some codes in the bash/Ubuntu/Xming environment on a
Windows machine (a new Dell laptop, 64 bit).  One item in particular that
I'd like very much to get running is seg2segy, as I'm not aware of too many
other options for converting SEG2 to SEGY.  I'm definitely not very
proficient at compiling, but I've been stuck on this for several days and
would be glad for suggestions.  I've installed a number of libraries to get
this to compile, via apt-get, and do get it to (seemingly) compile.  But
the executable doesn't actually work.  I've got two main options at this
point:


   If I compile with "gcc -m32 seg2segy.c  -Bstatic    -o seg2segy", and
then attempt to run the executable, I get this message " -bash: ./seg2segy:
cannot execute binary file: Exec format error".  My understanding is that
this indicates that the executable was compiled for an incorrect type of
system.  But I don't entirely understand what that means in this case.
I'm not too sure whether I ought to be using the -m32 flag, but that's
what's indicated by the note in the Makefile.  If I use that flag, in order
to avoid a compile error regarding "fatal error: sys/cdefs.h: No such file
or directory",  I need to install either/both of g++-multilib
or libc6-dev-i386.


   If I compile with "gcc seg2segy.c  -Bstatic    -o seg2segy" (same as
above, just without the -m32 flag) then I get an executable that runs, but
that rejects the SEG2 files I've tested it on, giving this message (I'm
including my command):
 > ./seg2segy 329.dat 1
Using default header word mappings.
File 329.dat, Data Format Revision: 1, Number of traces: 3
Not a SEG-2 trace header.  Can not process 3a55 (line 740)

   I've tested on a few SEG2 files, including the one that comes with SU in
the ThirdParty directory, with the same result.

Thank you very much for any suggestions on this.

Seth

try  suascii bare=4   (gnuplot)

SUASCII - print non zero header values and data in various formats

 suascii <stdin >ascii_file

 Optional parameter:
    bare=0     print headers and data
        =1     print only data
        =2     print headers only
        =3     print data in print data in .csv format, e.g. for Excel
        =4     print data as tab delimited .txt file, e.g. for GnuPlot
        =5     print data as .xyz file, e.g. for plotting with GMT

Use suwind/suresamp to make the files same length/sampling for comparison

suwind skip=2 count=1 < name1.su > selected_traces.su
suwind skip=66 count=1 < name2.su >> selected_traces.su
suwind skip=4 count=1 < name2.su >> selected_traces.su

suxwigb < selected_traces.su label2="Trace" label1="Time"

resrtict to first N samples of the traces
suwind skip=4 count=1 < name2.su itmax=N >> selected_traces.su

Hi

if you really need a time trace alongside the amplitude trace

sunull nt=1000 | sugain bias=0.001 | suop op=sum | sustrip | b2a n1=1

sunull nt=1000 | sugain bias=1 | suop op=sum | sugain scale=0.001 |
sustrip | b2a n1=1

will give you ascii values from 0.001 to 1 for instance (the second line
has smaller? float coding errors)


I'm pretty sure that in gnuplot you can take advantage of the constant
sampling rate of the trace to avoid to compute a time trace

For your last question,

you can also use psmerge to merge different eps outputs as layers (with
different sampling rates, number of samples etc). You have to fix the
boundaries and tic marks of your plots in order to have a good
superimposition.

D.

PS : I'm pretty happy that this mailing list is still up and running ! I
don't want to unsubscribe...

Subject: [Seisunix] Trouble compiling seg2segy

Hi Seth,

I had a similar problem some time ago? and I solved it by converting 
SEG2 file directly to the SU format.? Once in .su format you can convert 
to segy easily.

I downloaded,? compiled sioseis (gfortran) and ran its conversion options.

The following code is taken from inside a "for-loop" that works over 
many files, where each file name is an indexed element ($i) of an array 
of file names.

For example, $file_name[$i] represents the "ith" element of the array of 
file names ( strictly @file_name).
So if you are not familiar with the perl syntax, just replace 
$file_name[$i] with a single file name.

The only catch is that sioseis expects SEG2 file names to have a suffix 
= ".DAT".? My seismograph outputs ".dat" files that have to first be 
converted.

A second "gotcha" is that I usually have to run 'segyclean' on the output.

In any case, it you need a quick conversion, just send me the files and 
I can send them back converted.? I work on 64-bit machines under CentOS7.

sioseis << eof
procs seg2in diskoa end
seg2in
ffilen $file_name[$i] lfilen $file_name[$i]end
end
diskoa
opath $file_name[$i].su
ofmt 1
format su end
end
end
eof

Cheers,

Juan
