about EMEGS (Qt version)

EMEGS (Electro Magneto EncaphaloGraphy Software), the software for psychophysiological research. 

Visit us at  http://www.emegs.org/!

This is a Qt-based software extending the functionality of the original matlab software.



EMEGS (Qt version) is built with Digia's open source cross-platform GUI library "Qt", available under the terms of the LGPL v2 at ...

"http://qt-project.org/": Qt is a full development framework with tools designed to streamline the creation of applications and user interfaces for desktop, embedded and mobile platforms.

Statistical testing is done using the "R"-software for statistical computing, available at http://www.r-project.org/...

"http://www.r-project.org/": R is a language and environment for statistical computing and graphics. It is a GNU project which is similar to the S language and environment which was developed at Bell Laboratories (formerly AT&T, now Lucent Technologies) by John Chambers and colleagues. R can be considered as a different implementation of S. There are some important differences, but much code written for S runs unaltered under R.

Data exchange with R is performed with the help of the TCP-Server "Rserve" and the included C++ client, available at http://www.rforge.net/Rserve/ under the terms of of the LGPL.

"http://www.rforge.net/Rserve/": Rserve is a TCP/IP server which allows other programs to use facilities of R from various languages without the need to initialize R or link against R library. Every connection has a separate workspace and working directory. Client-side implementations are available for popular languages such as C/C++, PHP and Java. Rserve supports remote connection, authentication and file transfer. Typical use is to integrate R backend for computation of statstical models, plots etc. in other applications
