Microarray and 2D gel experiments are used for the large scale measurement, and comparison of gene expression. Since these experiments generate large and complex amounts of data, a great challenge the researcher faces is trying to find ways to analyze this data. This paper focuses on the tool DiffExpress, which was designed to make the gene expression analysis process easier. One of the main features of DiffExpress is the user defined threshold which allows users to set their personal restriction of the expression change at which genes are differentially expressed. DiffExpress also makes use of graphs such as the Scatter Plot, Box and Whisker Plot and Volcano Plot for easier visualization of data.
