Problems with sucdpbin
by JUAN LORENZO DIAZ NAVEAS 06 Apr '23

06 Apr '23

Dear SU users, I am trying to make the CMP binning of a seismic line (see the headers ranges below). The command line is: *sucdpbin < so104-17_geom.su <http://so104-17_geom.su> xline=723715,920883 yline=7242464,7237825 verbose=2 dcdp=25 distmax=500 > so104-17_cdp.su <http://so104-17_cdp.su>* As you see I have used a distmax of 500m and still I am not able to get the binning. Just in case I also tried again the same command, but sorting the date so that the first traces in the su file correspond to the minimum x coordinate and the last traces to the maximum coordinate (in the field the line was shot from east to west), but it failed as well. Any help would be very much appreciated. Best wishes Juan *466560 traces:tracl 1 513204 (1 - 513204)tracr 1 513204 (1 - 513204)fldr 1 3888 (1 - 3888)tracf 1 120 (1 - 120)ep 1 3888 (1 - 3888)trid 1nhs 1offset 413 3388 (3388 - 413)scalel -10000scalco -10000sx 723302 917547 (917547 - 723302)sy 7237924 7242471 (7237924 - 7242471)gx 723715 920934 (920934 - 723715)gy 7237823 7242464 (7237823 - 7242464)counit 1ns 3585dt 4000gain 9afilf 102afils 209lcf 3hcf 102lcs 6hcs 209year 1995Shot coordinate limits: North(-91.7547,-723.792) South(-72.3302,-724.247) East(-72.3302,-724.247) West(-91.7547,-723.792)Receiver coordinate limits: North(-92.0934,-723.782) South(-72.374,-724.246) East(-72.3715,-724.246) West(-92.0934,-723.782)Midpoint coordinate limits: North(-91.924,-723.787) South(-72.3521,-724.247) East(-72.3509,-724.247) West(-91.924,-723.787)* ------------------------------------------------------------------- Juan Diaz Naveas (Dr. rer. nat.)

Announcing Incremental release 44R28 of Seismic Unix
by John Stockwell 23 Mar '23

23 Mar '23

This release does contain a fix for the “types.h” (tirpc) installation problem seen by users on Ubuntu 22.04. I have also started adding platform specific installation instructions on https://wiki.seismic-unix.org <https://wiki.seismic-unix.org/> under Documentation. Right now this includes a list of all the packages that you need to install under Ubuntu 22.04 before you can install SU.

Dear All, Has anybody struggled with compiling version 44.26 and having trouble when compiling with the xdr I am getting messages like src/su/lib/fgettr.c:148: undefined reference to `xdr_float' src/su/lib/fputtr.c:123: undefined reference to `xdr_vector' I am running Ubuntu 22.04 and somehow, although xdr.h is installed at rpc/xdr.h I am not sure why the compiler does not locate it. Anu suggestions. -- Ramon -------------------------------------------------------------------------------------------- Ramon Carbonell CSIC-GEO3BCN GeoSciences Barcelona (http://Geo3BCN.csic.es/) https://orcid.org/0000-0003-2019-1214

That's because it's a linking error, the compiler found your include but the linker doesn't know it needs to use an additional library.

Help with fixing Trace number
by eloraafrin5＠gmail.com 08 Dec '22

08 Dec '22

Hello greetings! I am a beginner. I have a big su file with huge shot points, but I want to see a particular shot point in reduced velocity mode. I made a single file for those particular shot by using key=fldr. Now this file should have total 636 traces. I wrote a command suwind < indut su file key=tracl max=636 ....... However, in image I got values from2.84*10^5 to 2.85*10^5. Even when I want to see the image in reduced velocity mode, I need to set rv= >1000 whereas it should be rv=1 to 2. It seems like there are something wrong with units in the headers. Would anyone please help me with how can I fix these??? I am a new user; I will appreciate your help and time. Here I attached the header info. Thanks FYI 636 traces: tracl 1 636 (1-636) tracr 284929 285564 (284929-285564) fldr 2245 tracf 1 636 (1-636) cdp 2245 offset 112464 120401 (112464-120401) sx 376962 sy 5176643 gx 376962 gy 5176643 ns 2001 dt 4000

How to handle trace header information?
by tanahashi.m＠gmail.com 11 Nov '22

11 Nov '22

Dear all, I have performed a time resample of some 500ns sampled 3D seismic data to 1ms intervals using the suresamp command as shown below, but was unable to transcribe the 189-192 bytes of the Inline and the 192-196 bytes of the crossline numbers. segyread tape=Source3D.sgy|suresamp rf=0.5|segyhdrs|segywrite tape=Output3D_1ms.sgy I solved this problem by using the ASCII input/output function for trace header on SeiSee, a free Windows software, to write out the header information of the original file and then write it into the header of the output file. Is there a way to transcribe inline and crossline numbers using the SU function? Manabu Tanahashi Tsukuba, Japan

27 Oct '22

Hello, I am a beginner. I need to apply sureduce command to a particular shot which is in su file format. I tried with different rv values but could not see any differences in the image. I checked with the headers of that file and found I have ns and dt headers but not offset. Can anyone please help me how can I add offset header to my su file? And please let me know if there are any other things to fix to get result. Thanks

The SU list manager is (at least partly) broken
by Dominique ROUSSET 17 Oct '22

17 Oct '22

Hi SU users The SU list manager is broken. At least no new subscription is possible. The las one is dated 09/23. Sticking to mailman2 inhibits the upgrade of the whole hosting system (yunohost.org). I plan to upgrade to mailman3 soon, keeping as much information as possible from the present mail server. Don't worry if you receive automatic or test messages in the next hours or days. D. BTW: I don't know if this message will be transmitted :-) -- |Dominique Rousset LFCR UMR5150 / E2S UPPA / Dpt des géosciences| |Univ.
