It has been renamed Mage, this module.
Examples: genome tiling experiments, or multiple samples per array (Agilent and Illumina arrays).
There is a many-to-many between samples and hybridizations using the assay_biomaterial table. You assign your sample channel using the assay_biomaterial.channel attribute for a multi-channel array. Each tiling array hybridization in a tiling set would be considered a separate assay, and each would have a different assay.arraydesign_id.
