Figure 1From: ArrayWiki: an enabling technology for sharing public microarray data repositories and meta-analysesDiagrams showing the loss of data and precision during microarray processing. * Electron microscopy image of a microarray (adapted from reference [39]). In [20], the authors predict that 90% of CEL files generated from microarray experiments have never been deposited to any repository. Our own searches find only 6 experiments in GEO with associated DAT files.Back to article page
