Substantial contributions from Y. Debab and P. Willendrup.

If you produce scientific output using iFit, I'd appreciate if you cite the following reference:

- E. Farhi, Y. Debab and P. Willendrup, J. Neut. Res., 17 (2013) 1. DOI: 10.3233/JNR-130001
- E. Farhi, The iFit data analysis library, ILL, Computing for Science (2011) <http://ifit.mccode.org>.

Disclaimer:

This software is experimental, and should not be considered bullet-proof. In particular, expect many bugs - which should be reported to me [farhi (at) ill.fr] if you want them to be fixed quickly.

In short, you can use, copy, distribute and modify the Code. However, a number of restrictions apply, especially when producing derived work (that is modify and redistribute the code in other products). In particular, the derived work must be licensed under the EUPL or a Compatible License, label all modifications explicitly, distribute the Source Code, and cite the Original work.

Basically this is open-source. Use it if you find it useful, and enrich it.

If you do produce new methods, please send them back to me so that they are added in the software and thus benefit to the community.

A number of additions, included in the software, where obtained from the Matlab Central contributions, and are BSD licensed.

Matlab is a registered trademark of The Mathworks Inc. Related software (e.g. Matlab Compiler Runtime and Matlab) are covered by specific licenses.

I am currently the only developer of this project, which has been slowly designed for 10 years before writting the iFit basic project architecture. An initial prototype, specnd, was written earlier in years 2003-2004, then re-written from scratch with some of the current design principles in 2006 by Y. Debab [trainee at ILL] and me. The final project contains about 55000 lines of code (as of May 10th, 2011). About 10000 lines of code are contributed form other authors (see credits list below).

Note: This clearly shows that I can work as 9 guys in a row, and I'm dramatically under-paid. In fact I estimate I have worked about a total of one man-year on iFit over the last ten years.
