Data Format conversion

Often, it is necessary to transfer data from other systems, or to input data which may be in a variety of formats. A number of tools and tricks are available in SU for dealing with these issues.

The following programs may be useful for such conversion problems

• A2B - convert ascii floats to binary
• B2A - convert binary floats to ascii
• FTNSTRIP - convert Fortran floats to C-style floats
• FTNUNSTRIP - convert C-style floats to Fortran-style floats
• H2B - convert 8 bit hexidecimal floats to binary
• RECAST - RECAST data type (convert from one data type to another)
• TRANSP - TRANSPose an n1 by n2 element matrix
• FARITH - File ARITHmetic - perform simple arithmetic with binary files
• SUADDHEAD - put headers on bare traces and set the tracl and ns fields
• SUSTRIP - remove the SEGY headers from the traces
• SUPASTE - paste existing SEGY headers on existing data
• SWAPBYTES - SWAP the BYTES of various data types
• SUSWAPBYTES - SWAP the BYTES in SU data to convert data from big endian to little endian byte order, and vice versa

The purpose of this section is to discuss situations where these programs may be used.
