About the IsoGeneGUI
The IsoGene Graphical User Interface (IsoGeneGUI) is a user friendly interface of the IsoGene package which is aimed to perform analysis of dose-response studies in microarray experiments. The IsoGeneGUI is developed for the user with no or limited knowledge about R programming so he/she can perform the analysis of dose-response in microarray setting easily. This GUI was developed using tcl/tk.
The main window of the package is presented below.

The GUI has four main menus and in the middle of the window there is an info box. The package has four main menus: File, Analysis, Plots and Help.
