Hi,<br><br>I konw the sm_nearneighbor is base on GMT`s nearneighbor,<br>but the "nearneighbor" in GMT do not have a -w(in lower case) option ,<br>I just know it is used to compute the pga_rock.grd(or pgv_rock.grd) with sm_nearneighbor`s <br>-G ouput,but I dont know what it is.<br> so what`s the output of SM`s sm_nearneighbor with -w(in lower case)option??<br><br>codes in grind maybe at line 1340 :<br>$cmd = "$cfname -G$nnoutc -W -w$nnwgtc $grdpars -S$gmroi "<br> . "-D$gmdecay -E0 -N16/1";<br> print STDERR "Running 'sm_nearneighbor $cmd'\n" if $debug;<br> `$shakebin/sm_nearneighbor$v $cmd`;<br><br>Yes, I want to know what $nnwgtc is here!<br><br><br>Thanks,<br>WSC<br>
