Grid is a rapidly growing new technology that will provide easy access to vast amounts of computer resources, both hardware and software. As these resources become available soon, more and more scientific users are interested in benefiting from them. At this time the main problem accessing Grid is that scientific user usually need to know a lot about Grid methods and technologies besides their own field of application. This paper describes a toolkit which is based om Grid Services designed especially for the field of process data processing providing database access and management, common methods of statistical data analysis and project specific methods. The toolkit will fill to some extent the gap between high-level scientific Grid users and low-level functions in Grid environments, thus simplifying and accelerating the development of scientific Grid applications.
