Dear Giulia,

Yes, you can merge your SU files as indicated. The traces of the resulting file can be renumbered with header parameter 'tracl' (or 'tracr') via:

sushw  <  onesection.su  key=tracl  a=1  b=1  >  onesection_modified.su

You can check that operation with:

suedit  onesection_modified.su

which displays the header values of the last trace of your file (type 1 to see the header values of trace 1).

You can then proceed with the SU to SEG-Y conversion if that is your goal.

Best wishes,

Michel

Dear Sirs,

I have some scanned seismic image I am converting in segy data format.

Having all sections the same number of time sample and the same sample interval, but of course different trace number, I need to have only one segy.

 

May I apply a command like: cat section1.su section2.su section.su > onesection.su

 

If it is possible, then I need to renumber the trace number and I think to use sushw module but I do not find which is the key word to renumber the trace number.

 

Thanks to All.

 

Giulia
