Sample and Data Relationship Format

The Sample and Data Relationship Format (SDRF) is part of the MAGE-TAB standard for communicating the results of microarray investigations, including all information required for MIAME compliance.

An SDRF file is a tab-delimited file describing the relationships between samples, arrays, data, and other objects used or produced in a microarray investigation.

For simple experimental designs, constructing the SDRF file is straightforward, and even complex loop designs can be expressed in this format.
