What is MyCGR ?
MyCGR is an Objective-Caml library and a collection of tools to use the Chaos Game Representation on DNA sequences.

This software is experimental. It was developed during the thesis of Peggy Cénac and can be used to run the simulations and experiments described in this thesis. This software (including the source code) is made available to allow its use and the addition of functionalities within the framework of other research.


Source code is available (22 Jun 2006 15:10:00 +0000)
Version 0.98 is available for download and the development site is now public.

Site on line (18 Apr 2006 15:30:00 +0000)
The MyCGR site is now in line. The software will be available soon.

The instructions to download and install the MyCGR software are on this page.

Library Reference: reference documentation on the Cgr library, an Objective-Caml library included in MyCGR. This library offers modules to manipulate DNA sequences, compute CGR, perform tests on structures of sequences, compute distances between species, ...

Overview of tools: a nonexhaustive list of the programs included in MyCGR, with their main functionalities.

First steps: indications to start to use MyCGR.


Some results of simulations carried out with MyCGR are available on this site:
