The corresponding computational problem is very computationally intensive. We have earlier shown that, using appropriate parallelization schemes, this type of application is suitable for deployment on grid systems. A grid portal interface is often an ideal tool for biologists performing advanced genetic analysis. We describe an implementation of such a portal system and how it is used for performing multidimensional QTL searches efficiently.} }
