MIAME ‘checklist’ to authors and reviewers • Experimental design • Samples used, RNA extraction and labelling • Hybridisation • Measurement data and specifications • (Raw images) • Image quantitation (data and specification) • Gene expression data matrix (data and transformations) • Array design
Nature and The Lancet is adopting compliance to MIAME checklist as a requirement for publishing microarray papers!
Questions • Is MIAME a good or a bad idea? • Is everything what is included in MIAME really necessary for data sharing? • Is something missing? • How would you like MIAME to be changed? www.mged.org/miame
