The Madagascar project has been in public existence for five years. Madagascar provides a complete environment for organizing one's research, from new software development to running computational experiments to publishing the experimental results in papers and reports, archiving them for future usage, and sharing them with colleagues and sponsors. The introductory presentation will describe the history of the project, the Madagascar components and design principles, and the future development goals.<br><br>

Madagascar programs are designed to run from UNIX shell. In this tutorial I will show command-line usage of some basic Madagascar programs and how to manage data flow between different programs. I will also explain the working mechanism of RSF format and how to represent RSF dataset graphically using Madagascar programs.<br><br>

[http://www.scons.org/ SCons] (from '''S'''oftware '''Cons'''truction) is a superior alternative to the classic '''make''' utility. SCons is implemented as a [http://www.python.org Python] script, its "configuration files" (<tt>SConstruct</tt> files) are also Python scripts. Madagascar uses SCons to compile software, to manage data processing flowing, and to assemble [[Reproducible Documents|reproducible documents]].<br><br>

|-
|
| colspan="2"  |
Writing a Geophysics paper using Madagascar offers features beyond the conventional LeTeX package. It first adheres to reproducible principals, which allows for seamless team work and access to your work by others and by your self down the road. It also offers a treasure chest of reproducible papers, which can serve as templates and examples. We will look into these features and write a reproducible paper, at least start one, together.<br><br>

! colspan="2"  |  Wave-equation modeling and migration (Paul Sava) 
|-
|
| colspan="2"  | 
The theoretical part of this module provides an overview of reverse-time imaging methodology applied to wavefield seismic data.  The main technique discussed is reverse-time migration with emphasis on modern imaging conditions which enable migration velocity analysis and amplitude-versus-angle analysis. The applied part demonstrates this technique on a complex geologic model using Madagascar codes in a fully reproducible setup.<br><br>

Field data processing is an important test of integrality degree for open-source software and the final target for scientific research. We will use a 2-D field dataset to illustrate how Madagascar can set up a common seismic data processing workflow.<br><br>

! colspan="2"  | Developing your own programs in Madagascar (Jeffrey Shragge)
|-
|
| colspan="2"  | 
There are many programs already built into the Madagascar project, but if you use Madagascar long enough you will eventually run into a problem that you cannot solve using only provided codes. Fortunately, Madagascar has a variety of programming language APIs already built, that allow you to: design, code, and integrate your programs into the Madagascar framework. By the end of the session, you should have a good starting point for developing your own codes, and adding them to the growing library of open-source software available in Madagascar. <br><br>

|-
|
| colspan="2"  |
As a user of Madagascar, you have the right to run the code for any purpose, to make modifications and additions, and to share your modifications with other people. Madagascar is an open community, which makes it easy to share your contributions and to collaborate with other users and developers around the world. <br><br>
