string bfile= | output binary data header file
|
bool endian=y [y/n] | Whether to automatically estimate endianness or not
|
int format= [1,2,3,5] | Data format.
The default is taken from binary header for segy input.
Default is 5 for su input.
1 is IBM floating point
2 is 4-byte integer
3 is 2-byte integer
5 is IEEE floating point
6 is native_float (same as RSF binary default)
|
string hfile= | output text data header file
|
string mask= | optional header mask for reading only selected traces (auxiliary input file name)
|
int n2=0 | number of traces to read (if 0, read all traces)
|
int ns=0 | Number of samples. The default is taken from binary header
|
int nsbyte=0 | byte number for ns in binary header
|
string read= | what to read: h - header, d - data, b - both (default)
|
bool su= [y/n] | y if input is SU, n if input is SEGY
|
bool suxdr=n [y/n] | y, SU has XDR support.
SU with xdr on (as downloaded), use endian=y suxdr=y
SU with xdr off in the makefiles, use endian=n suxdr=n
|
string tfile= | output trace header file (auxiliary output file name)
|
bool verb=n [y/n] | Verbosity flag
