According to the virtual physiological human paradigm, integration is often\break required among different levels and disciplines. Large, distributed and heterogeneous repositories, as well as computationally demanding analysis tools, are more and more involved in biomedical studies. Both for storage of distributed biomedical data and metadata and for access to distributed analysis tools, a Grid-based approach may provide a shared, standardized and reliable solution. To make users able to easily access available services and data, a Grid portal has been implemented in order to hide the complexity of the framework. The portal is intended to act as Grid services provider and as Web interface for managing workflow enactment and management on the Grid. Workflows may be submitted as Grid jobs through a service-based workflow engine and monitored during execution. As a first case study for testing workflow functionalities of the Grid portal, an application is presented for the search and analysis of microarray data. |
