Biology:Sample and Data Relationship Format

From HandWiki

The Sample and Data Relationship Format (SDRF) is a tab-delimited file describing the relationships between samples and data in fields such as genomics and proteomcs. The format originated as part of the MAGE-TAB standard for communicating the results of microarray investigations, including all information required for MIAME compliance.[1] It was later extended to, and is currently primarily used for, next generation sequencing and proteomics.[2]

For simple experimental designs, constructing the SDRF file is straightforward, and even complex loop designs can be expressed in this format. In practise, tools such as lesSDRF [3] are often used to annotate experimental metadata in SDRF.
