SYNOPSIS

SEISMIC UNIX NOTES SUXEDIT - examine segy diskfiles and edit headers

 suxedit diskfile  (open for possible header modification if writable)	

 suxedit <diskfile  (open read only)					



 The following commands are recognized:				

 number	read in that trace and print nonzero header words	

 <CR>		go to trace one step away (step is initially -1)	

 +		read in next trace (step is set to +1)			

 -		read in previous trace (step is set to -1)		

 dN		advance N traces (step is set to N)			

 %		print some percentiles of the trace data		

 r		print some ranks (rank[j] = jth smallest datum) 	

 p [n1 [n2]]  	tab plot sample n1 to n2 on current trace		

 g [tr1 tr2] ["opts"] 	wiggle plot (graph) the trace		

				[traces tr1 to tr2]			

 f		wiggle plot the Fourier transform of the trace		

 ! key=val  	change a value in a field (e.g. ! tracr=101)		

 ?		print help file						

 q		quit
