seisunix's Issues

Possible leak in suamp.c

Hi John

Just stumbled over this

SeisUnix/src/su/main/transforms/suamp.c

Line 267 in 4368a92

phase = alloc1float(nfby2);

Shouldn't the array used for the different phase unwarpping modes be allocated outside the loop over traces, and free'd after.
As it is now I think there is leak

seg2segy - Not a SEG-2 trace header. Can not process 3a55 (line 740)

Good afternoon.

I'm having some issues using seg2segy on my macOS 10.15.1 device. I've compiled SeisUnix and seg2segy, but when I run seg2segy 329.dat 1 using the included .dat file, I receive the following error:

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)

If I try using seg2segy with a file that isn't .dat (such as the included 329.su file), it returns the following error:

Using default header word mappings.
Not SEG-2 data can not continue

Has anyone encountered this issue before? Given that it identifies that 329.dat is seg-2 data leads me to believe that the binary is functioning properly. Please let me know what other information I can provide that would help with troubleshooting this issue. Thanks in advance for any assistance!

Installing on MacOS Mojave

A note for anyone else who may have problems compiling on macOS Mojave.

I followed the first couple of instructions (as listed in the link below) to install the required system headers in the old locations:

https://solarianprogrammer.com/2017/05/21/compiling-gcc-macos/

It may be worth adding this step to the MacOS installation instructions on the wiki.

Building components in parallel fails

Taking advantage of multi-core systems by building CWP/SU with "make install -j #" (building with up to # parallel jobs) fails in a non-deterministic manner.

Underscores (_) don't convert properly to EBCDIC in segywrite

Lines 41-52 of zasc.c and zebc.c define these two tables:

static integer t1[96] = { 32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,
        48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,
        70,71,72,73,74,75,76,77,78,79,80,81,82,83,84,85,86,87,88,89,90,91,
        92,93,94,95,96,97,98,99,100,101,102,103,104,105,106,107,108,109,
        110,111,112,113,114,115,116,117,118,119,120,121,122,123,124,125,
        126,127 };

    static integer t2[96] = { 64,79,127,123,91,108,80,125,77,93,92,78,107,96,
        75,97,240,241,242,243,244,245,246,247,248,249,122,94,76,126,110,
        111,124,193,194,195,196,197,198,199,200,201,209,210,211,212,213,
        214,215,216,217,226,227,228,229,230,231,232,233,74,224,90,95,108,
        64,129,130,131,132,133,134,135,136,137,145,146,147,148,149,150,
        151,152,153,162,163,164,165,166,167,168,169,192,106,208,161,64 };

It seems to me that in the EBCDIC table t2, "108" (%) is listed twice as a translation for both ASCII 95 (_) and 37 (%). So eg. in segywrite, all underscores are converted to percent signs. Changing 108 to 109 on line 51 of both zasc.c and zebc.c and recompiling seems to fix the issue.

Reference: appendix F of SEG-Y rev 1 Data Exchange format (2002) or this translation table.

sukdmig2d without stacking

Hello Mr.Stockwell,
Is it possible to migrate the seismic using sukdmig2d without stacking the traces?
I enter the shot gathers as input on the Kirchoff Depth Migration, and as output the seismic is already stacked.
Sincerely Yours,
Matheus

Segmentation fault (core dumped) in running sureflpsvsh

Hello.

I am using 43R1 release.
when I try to run sureflpsvsh function, I get the "segmentation fault" error in BASH.
I saw somewhere on the web that the calculation of SH waves has had issues, so I tried to only run PSV, but still got the above message.

Is this a bug or am I doing something wrong?

Where are the other files on the mines ftp?

I'm trying to access the other files which were on the ftp server where SU was formerly hosted. Do you have any idea where these files are currently located?

(I'm specifically trying to access ftp://ftp.cwp.mines.edu/pub/data/oz.original/README)

Thanks.

Pre-Stack Time Migration by using Stolt Method

Hello Sir, I’d like to express my thanks to you for you support and helping us to be good in SU.
I have a new problem with stolt method.
In Pre-Stack migration.
The command that i using it in terminal window is
sustolt < cmpgather.su cdpmin=1 cdpmax=538 dxcdp=45 noffmix=-1475 1475 vmig=3000 tmig=0.00 > stoltgather.su
The work in terminal window is done and created empty file hav a name stoltgather.su

Where is the wrong with that ??

With my best regards,

Small bug/inaccuracy in sumax

Hi,

I believe there is a minor inaccuracy in the Seismic Unix sumax command. The problem arises when the maximum (or minimum) value occurs in the very first sample of a trace. Here is the relevant source code from sumax.c :

/* find local/global max/min values and their locations /
min = max = tr.data[0];
absmax = ABS(tr.data[0]);
tr.data[0] = 0.0; / Zero first data value /
trhldmax = tr.data[0];
trhldfit = (int) (trhldstrt / dt);
for (it = 1; it < nt; ++it) {
if (tr.data[it] > max) { / Find max */
max = tr.data[it];
maxit = it;
}

 if (tr.data[it] < min) {	/* Find min */
    min = tr.data[it];
    minit = it;
 }

It appears that if the trace maximum occurs in the very first sample, the condition if (tr.data[it] > max) is never satisfied. Consequently, the value of maxit is not updated, and sumax just inherits the maxit value from the previous trace. The same goes for minima.

I believe the issue can easily be fixed by adding the following two lines of code just after the statement min = max = tr.data[0];

maxit = 0;
minit = 0;

However, I am no coding expert, so I might be wrong about the solution.

Best Regards, and thank you for maintaining a very useful software package.

I am struggling with the installation instructions. Would someone be willing to outline the steps needed to install and configure SU on a Mac from the starting point of the git clone?

sustack: nhs of stacked traces is not summed up

Assume the input

tracl = 1, nhs = 2, cdp = 1
tracl = 2, nhs = 2, cdp = 1

the stacked result would be correctly initialize fold = trace_1.nhs = 2, but then just += 1 for every following trace, rather than += trace.nhs, thus resulting in

tracl = 1, nhs = 3, cdp = 1

rather than

tracl = 1, nhs = 4, cdp = 1

Since fold is initialized with the first trace's nhs, I assume this is intended behaviour, and https://github.com/JohnWStockwellJr/SeisUnix/blob/master/src/su/main/stacking/sustack.c#L182 needs to be patched to fold += intrace.nhs == 0 ? 1 : intrace.nhs;, i.e. do the same as for initialization of fold.

Errors when using 'make finstall' in Ubuntu 14.04

Hi John,

This is Min. I'm facing a problem when try to use ' make finstall ' command. It shows some errors as follows:

Could you tell me what might be the problem? Thanks!

installtion

Dear JohnWStockwelljr

I am writing to ask for your guide and assistance about installation and running procedure of ‘Fdelmodc’ on my ‘Linux ubuntu 18’. As you said on ‘Github’, I got ‘MKL’ from ‘Intel’ and it was installed. Now, unfortunately after doing all steps, I have the model but not the data. I would very much appreciate if you could send me an explanation video on YouTube about :

1- The installation process from first to last.

2- After running the model, with which format data will be stored.

Sincerely Yours

Can't use segdread

Hi,

I have some SEG D files to read, but the "segdread" doesn't work. It shows that "cannot execute binary file". Other SU tools work well. Thank you!

Cannot download SU from http://cwp.mines.edu/cwpcodes/index

I am a Chinese user who is required to use SU for one of my courses. However, I could not download the software from the website above or use wget in cygwin. IS there any where I can download the installation package?

error on installing improved SEGDREAD

while running the command
make sfinstall
I get a few errors:
fclose.c: In function ‘fclose’:
fclose.c:20:37: error: ‘stdin’ undeclared (first use in this function)
if((rv = sfclose(sf)) >= 0 && f != stdin && f != stdout && f != stderr)

^
fclose.c:20:66: error: ‘stderr’ undeclared (first use in this function)
if((rv = sfclose(sf)) >= 0 && f != stdin && f != stdout && f != stderr)

Then it goes on and finsh the installation. But when I test the installation by
suplane | suximage title="My first test" &

a figure appears, but then also I gets an error:
XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0"
after 2304 requests (2304 known processed) with 0 events remaining.

I am running Ubuntu 16.04 LTS

ar: libcwell.a: Malformed archive

When I run make finstall, it fails, saying:
make[2]: Warning: Archive 'libcwell.a' seems to have been created in deterministic mode. 'shoot.o' will always be updated. Please consider passing the U flag to ar to avoid the problem.
gfortran -g -ffixed-line-length-none -c -o shoot.o shoot.f
ar rv libcwell.a shoot.o
ar: libcwell.a: Malformed archive

I can follow those instructions to pass the U flag, by editing the Makefile.config file to set:
ARFLAGS = rvU
When I do that, it still reports the same warning, and says:
ar rvU libcwell.a shoot.o
ar: libcwell.a: Malformed archive

I am running Ubunto 18.04, code name bionic.

I notice this file, libcwell.a is supplied in the GitHub down load from $CWPROOT/src/Fortran/Cwell/libcwell.a, recently updated 'last month', with the comment 'Updated sugain.c'

Can I do anything to re-form this archive?

Data cannot be found.

Hi, I am self-study of your course GPGN 461/561 Lab, but the data in the course such as seismic.su, simple.su can not be found, so, how to solve it? Thank you.

Failed make install (openSUSE )

Hello,

my issue seems similar to #12 but I am not capable of figuring out what is the problem based on solutions presented in that issue.

I receive similar errors after executing make install command, however libtirpc and libtirpc-devel are already installed at my machine.

My /usr/include/ folder does not include tirpc folder, only rpc. So I have created a symbolic link: ln -s /usr/include/rpc/* /usr/include/tirpc/.
This hasn't changed to result.

I have installed all packages listed as prerequisites on the github page "Seismic Unix install on Linux".

My system is: openSUSE Tumbleweed
SU: 44R16 (downloaded from SU wiki page)

I use default Makefile.config file (I tried replacing it with Makefile.config_Linux_x86_64 but the result stays the same).

Thank you for your help!
Kind regards,
Feliks Sartorius

Inverse NMO

hello sir
is it possible to apply inverse NMO in seismic unix ??
or any way to modify sunmo program for applying inverse NMO ?

tau-p

Hi,
I have been trying to run my data set in tau-p domain in SU (SUTAUP and SUTAUPNMO) but this has proven difficult.
I think the reason is that the trau-p transforms of different CDPs only display with the same trace parameters for all cdps tested, making each cdp tau-p transform display on each other.
Please is there any way around this, as I have tried to change the header in SU but this is not helping.
I am not an expert in SU but because of its flexibility I wish to use it at this point.

When I tried to install SU I had a problem below. Someone had the same problem and knows how to solve it?

Segdread errors and install problems

Dear sir，
My system is Ubuntu 18.04 LTS.
I need segdread to convert some segd format data to su format data.
When I typing segdread, it shows:

suplane | suximage title="My first test" &

All the command like segyread, segyclean and suximage are OK for me. But I can not excute segdread.
Can you help me ?

Need tests that can be run automatically

Tests should be done such that they can be run without human interaction.

For example src/cwp/test/airybpt.c

• C / C++ testing frame works e.g. Google Test would work well
• Fortran testing frameworks
• Have an obvious top level pointer on how to run the tests
• Add CI to the project for the key platforms. e.g. Travis-CI for Linux and Mac build and test setups

Time and depth Migration using Kirchhoff.

Hello Mr. John StockwellJr.
I’d like to applying the Kirchhoff Migration in the time and depth methods using an synthetic model for 2D seismic survey line with the field parameters.
How I can using Kirchhoff in Time Migration for pre and post-stack time migration through SU.
Thanks & Regards sir.

Trouble with Velan.radon

Dear JohnWStockwellJr,
I am writing to report a problem in the Velan.radon script. When i am picking velocities on the semblance for multiple-supression, the script always raise this error : "sunmo: tnmo values must increase monotonically".
I have check in all ways if my picks are really correct, but i still have not found a solution for this.
I would very much appreciate if you could send me an explanation for this case.
Sincerely Yours

Error when compiling sunormalize.c

In the current build, the function void vrmedian had an error where it was trying to return an int value at the end. I corrected it for my installation by commenting this return value. Was that the right action or should I have redefined it to an int function?

Error when compiling fortran code under Ubuntu 18 LTS

I'm facing a weird error when using Ubuntu 18 LTS (64 bits) when compiling with

make finstall

The particular error comes in the vzest folder

make[2]: Entering directory '/home/angel/SeismicRoot/SeisUnix-master/src/Fortran/Vzest' gfortran ./vzestf.o ./vzestsubf.o ./vzestc.o -o /home/angel/SeismicRoot/SeisUnix-master/bin/vzest -lm /usr/bin/ld: ./vzestf.o: relocation R_X86_64_32S against .rodata' can not be used when making a PIE object; recompile with -fPIC
/usr/bin/ld: ./vzestsubf.o: relocation R_X86_64_32S against .bss' can not be used when making a PIE object; recompile with -fPIC /usr/bin/ld: final link failed: nonrepresentable section on output collect2: error: ld returned 1 exit status make[2]: *** [Makefile:17: /home/angel/SeismicRoot/SeisUnix-master/bin/vzest] Error 1 make[2]: Leaving directory '/home/angel/SeismicRoot/SeisUnix-master/src/Fortran/Vzest' make[1]: *** [Makefile:14: INSTALL] Error 2 make[1]: Leaving directory '/home/angel/SeismicRoot/SeisUnix-master/src/Fortran' make: *** [Makefile:126: finstall] Error 2

It's a weird error beacause the other installers work fine and also I'm able to install SU under Ubuntu 16 LTS (64 bits) without any error.

Edit:
Thanks for the answer
