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.

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
