for the purpose of this NOFO as initial tool development or the significant modification of existing tools for new applications. The central mission of ITCR is to promote research-driven informatics technology across the development lifecycle to address priority needs in cancer research. In order to be successful, proposed development plans must have a clear rationale for why the proposed technology is needed and how it will benefit the cancer research field. In addition, mechanisms to solicit feedback from driving research projects and other users throughout the development process must be included.This NOFO encourages applications that involve the development of new, user-friendly informatics technologies that support a wide range of cancer research, including discovery biology, population studies, as well as clinical and translational research. The emphasis is on uniqueness and potential impact on cancer research. In addition, all projects proposed in response to this NOFO must involve the following general attributes:Potential to advance driving cancer research projects and the cancer research field in generalNovel informatics capabilities for the targeted cancer research domainCompelling plans and processes for engaging end users to evaluate and apply the tool or resourceA realistic timeline and milestones for technology development
