TESD version 1.0
Transposable Element Simulator Dynamics, is a scientific application
developed by the Laboratoire de Biométrie et Biologie Evolutive (UMR CNRS 5558, Université Claude Bernard Lyon 1, France).
Based on "
transposable elements in structured populations", Deceliere et al. (Genetics 2005, 169: 467-474) have
developed the simulation core of TESD in an
object-oriented fashion. TESD simulates the number of genomic TE copies in different
populations across generations (according to the Island Model),
using classical models of TE dynamics. The parameters of the
models (transposition and excision rates, selection intensity,
recombination rate, migration rate, population sizes and number of
populations) are defined by the users.
To make it more user-friendly, TESD has a graphical interface. Users can set the various parameter values by using forms that ask questions. The results of the simulations are visualized thanks to built-in graphical tools, using the JFreeChart library.
TESD provides a complete application that allows modellers to implement other models of TE dynamics. TESD is implemented in Java, an object-oriented language that can be extended easily, and this means that TESD can be run on all Operating Systems (Linux, Mac, Windows, Solaris, etc.).
As TESD is a java application that uses JFreeChart libraries and JavaHelp Libraries, you will have to download the four following .jar files:
No "installation" is required if you already have the Java Runtime Environment (version 1.4.2 or earlier) on your computer; if not, click here. In any cases, the four .jar files must be placed in the same directory for TESD to work properly. To start TESD, depending on your Operating System:
TESD can also be used via a command line interface instead of the graphical one. This can be useful for experienced users planning, for example, to embed TESD in a script or to study its outputs with R.
See the Help Files for more
- Windows : simply double click on the TESD.jar file
- Mac : as above
- Linux : in a console, at the directory containing the .jar
files, enter : java -jar TESD.jar
