As part of the MouseExpress project of the German Human Genome Project (DHGP) we have set up a microarray database combined with an interactive analysis framework called ME.

ME's standard-conforming object-relational database handles all recent formats of high-density microarray systems (Oligo, Dendrimer, various cDNA/EST-array software formats) and is interlinked with various other data sources like PEDANT and MIPS FunCat (  ME's analysis framework handles data submitted to its database as well as directly uploaded data. It is a modular system with a broad variety of interfaces and is accessable at Direct and interactive statistics feedback for submitted data, especially genome-wide vertebrate expression profiles, is essential to ensure the quality of expression databases. Therefore, ME's online microarray data analysis framework offers a variety of easy-to-use online tools for this purpose which additionally allow researches to track the sources of variability.

ME allows for interactive functional analysis of various kinds of expression data with focus on dichotomic datasets (e.g. mutant-wildtype comparison).

For example, ME can be used to extract specific pathways or functional groups. This technique reduces signal variability due to features out of interest and puts results directly into the functional context.
