Hi Juan,

after a quick look at sucdpbin.c, i note that this tools honors the scalco keyword. So, since your data bear a -10000 scalco, you have to divide xline and yline parameters by 10000 to work with actual units, not with sx and sy units.

Let me know it it works Good luck !

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
