Science Gateways provide an easily accessible and powerful computing environment for researchers. These are built around a set of software tools that are heavily used by large research communities in specific domains. Science Gateways have been catering to a growing need of researchers for easy to use computational tools, however, their usage model is typically single user-centric. As scientific research becomes ever more team-oriented, the need for integrated collaborative capabilities in Science Gateways has been emerging. One such need is the ability to share data/results with others. In this article, we will describe and discuss our effort to provide a rich environment for data organization and sharing by integrating the SeedMeLab platform with two Science Gateways: CIPRES and GenApp.
