Madagascar (software)
Madagascar is a software package for multidimensional data analysis and reproducible computational experiments. Its mission is to provide for researchers working with digital image and data processing in geophysics and related fields. Technology developed using the Madagascar project management system is transferred in the form of recorded processing histories, which become "computational recipes" to be verified, exchanged, and modified by users of the system. Features. The Madagascar environment consists of: Example script. An example file is shown below from rsf.proj import * Fetch('wz.35.H','wz') Flow('wind','wz.35.H','dd form=native | window n1=400 j1=2 | smooth rect1=3') Plot('wind','pow pow1=2 | grey') Flow('mute','wind','mutter  v0=0.31 half=n') Plot('mute','pow pow1=2 | grey') Result('denmark','wind mute','SideBySideAniso') End() Note that by itself does not do any job other than setting rules for building different targets. The targets get built when one executes on the command line. Running produces License. Madagascar is free software and is licensed under the GPL. History. Madagascar was first publicly presented at the EAGE Workshop in Vienna in June 2006. The work on the package (previously named RSF) was started by Sergey Fomel in 2003. Since then, many people have contributed to it. While being written mostly from scratch, Madagascar borrows ideas from  the design of SEPlib, an open-source package maintained by Bob Clapp at the Stanford Exploration Project (SEP). Generations of SEP students and researchers contributed to SEPlib. Most important contributions came from Rob Clayton, Jon Claerbout, Dave Hale, Stew Levin, Rick Ottolini, Joe Dellinger, Steve Cole, Dave Nichols, Martin Karrenbach, Biondo Biondi, and Bob Clapp. Madagascar also borrows ideas from Seismic Unix (SU), a package maintained by John Stockwell at the Center for Wave Phenomenon (CWP) at the Colorado School of Mines (Stockwell, 1997; Stockwell, 1999). Main contributors to SU included Einar Kjartansson, Shuki Ronen, Jack Cohen, Chris Liner, Dave  Hale, and John Stockwell. SU adopted an open-source BSD-style license starting with release 40 (April 10, 2007). Madagascar Schools. Madagascar Schools on Reproducible Computational Geophysics are annual events, where new users get introduced to the package, and project participants meet to discuss new developments. Here is the list of previous schools:
