SU to m8r dictionary

Seismic Unix (SU) is a software package for seismic data processing. The dictionary below is intended for SU users who are interested in either using Madagascar (m8r) or in finding out which algorithms/utilities are present in m8r, but not in SU.

A m8r program, or a chain of m8r programs, will be considered equivalent to a SU counterpart only if it has at least all the capabilities of its SU counterpart. For example, a m8r program that requires regularly sampled data, and cannot take position information from auxiliary files, but just works on a hypercube, cannot be considered by itself the equivalent of a SU program implementing an equivalent algorithm and working on an actual irregularly sampled grid. However, a cascade of a m8r regularization program and a program working on a regularly sampled cube can be considered equivalent to a SU counterpart if the approximations introduced by regularization do not matter.

The starting point of the list below was Chris Liner's help page for Seismic Un*x v.38.
