Introduction to the CSSI DCC Portal

Data repositories are important tools in cancer research, providing safe and sustainable locations to store data, providing access to input data for meta-analyses, and allowing researchers to collaborate and share information across a common resource. The Center for Strategic Scientific Initiatives (CSSI) sponsors a diverse array of projects that generate datasets that vary in content and format, yet are related across certain defining characteristics or metadata. Integrated management of the datasets across all sponsored projects make the data more accessible, easily accessed, and potentially reused by the cancer research community. 

The CSSI Data Coordinating Center (CSSI DCC) stores and manages access to data generated in support of cancer research funded or supported by the CSSI. This data is in the standard Investigation-Study-Assay tab-delimited format (ISA-TAB) format, which describes a scientific investigation, its study or studies, and each study's assay(s). For more information on the ISA-TAB format, refer to the following section, Chapter 1: Getting Started with the CSSI DCC Portal What is ISA-TAB?, as well as the ISA-TAB specification

What is ISA-Tab?

Investigation-Study-Assay tab-delimited format (ISA-Tab) is a format based on the ISA-TAB specification that is used to capture and communicate the complex metadata required to interpret investigations (experiments) employing combinations of technologies. Metadata in ISA-Tab format facilitates standards-compliant collection, curation, management, and reuse of datasets in a wide variety of life science domains. ISA-TAB builds on the existing paradigm that is Microarray Gene Expression - Tabular format (MAGE-TAB)-a tab-delimited format to exchange microarray data.
