Specialized software, on-line tools and computational resources are very common in contemporary science. One of the exem- plary domain is genomics - a new branch of science that developed rapidly in the last decade. As the genome research is very complex, it must be supported by professional informatics. In a microarray field the following steps cannot be performed without computational work: design of probes, quantitative analysis of hybridization results, post-processing, and finally data storage and management. Here, the gen- eral aspects of virtual laboratory systems are presented together with perspectives of their implementation in genomics in order to automate and facilitate this area of research.

In this work authors discuss the various aspects and problems connected with interactive jobs' management in the grid environment. The specific nature of scheduling the interactive experiments is closely analyzed, revealing the complex approach that has to be taken into account in order to consider many new, scientific-domain scheduling factors. Diagrams for submission, launching, prolonging and ending the interactive sessions are proposed. Presented idea is generic and can be used in many grid-based systems. The grid broker e.g. Grid Resource Management System (GRMS) is required in our conception and we assume its presence in the environment.

In the paper some dynamic measurement scenarios conception is presented. The dynamic measurement scenarios (DMS) are used for advanced workflow control in the virtual laboratory system. It facilitates defining and monitoring the measurement process from the preparation stage through experimental and computational processes to results analysis (based on the achieved visualization data). DMS often consists of many different tasks connected by links with specified conditions. To execute DMS we need a special application (during the definition process) on the one hand and on the other hand a sophisticated (and complex) module is needed for manage and control specified workflow. The described issues are illustrated by nuclear magnetic resonance (NMR) laboratory examples.
