As I needed a way to validate the Seismic File compression programs, I decided to write a file difference program.
Actually it can do a bit more – Addition, Multiplication sand division as well as subtraction.
So it could have been called Seis File Arithmetic, but an acronym of SFA is probably not the best one to use,
so I have called it Seis File Difference or SFD.
It also allows for pre and post scalars so that data sets recorded with different parameters can be compared.
It will even compare files from different systems and formats, with the caveat that the number of channels and the sample rates must be the same.
If record lengths are different, the shortest is used.
Very easy to use, just select the two files you want to compare, specify the operation, the output file
and desired options, click Go and a SEGY result file will be generated.
