{scrollbar:icons=false} h1. Question: What are MAGE-TAB Files? *Topic*: caArray Usage *Release*: caArray 2.X *Date entered*: 02/12/2009 Topics on this page include the following: {toc:minLevel=2} h2. Answer MAGE-TAB (MicroArray Gene Expression Tabular) format files refer to simple tab-delimited, spreadsheet-based files, which can be used for annotating and communicating microarray data in a [MIAME compliant fashion|http://www.mged.org/Workgroups/MIAME/miame.html]. MAGE-TAB specification is based on the [Microarray and Gene Expression|http://www.mged.org/Workgroups/MAGE/mage.html] Object Model ([MAGE-OM|http://www.mged.org/Workgroups/MIAME/miame_mage-om.html]). MAGE-TAB [specification|http://www.mged.org/mage-tab/spec1.0.html] and related [publications|http://www.biomedcentral.com/1471-2105/7/489] provide more details on the format. The following table summarizes the definition of each MAGE-TAB format file. {color:red} replacing table{color} For more information see [MAGE-TAB in caArray--Overview|https://wiki.nci.nih.gov/x/Oxo9Ag#7-SubmittingDatatoanExperiment-MAGETABincaArrayOverview] {text-extractor}{multi-excerpt-include:MAGE-TAB_definitions |name=relationship|nopanel=true} MAGE-TAB files imported into caARRAY map to data files also imported into the same caARRAY experiment.

Building MAGE-TAB Formatted files Because of the varied nature of every caArray experiment and its corresponding data, it is impossible to outline the exact steps for creating a caArray-compatible MAGE-TAB file. There are strict guidelines, however, for characteristics of MAGE-TAB files that meet the criteria. Refer to [Appendix A - MAGE-TAB in caArray|https://wiki.nci.nih.gov/x/Rho9Ag] in the caArray User's Guide for specific details regarding caArray-compatible MAGE-TAB files. To provide context, see the [MAGE-TAB Specification document|http://www.mged.org/mage-tab/spec1.0.html]. To get started, you can generate a MAGE-TAB template file from [EMBL-EBI's MAGE TAB site|http://www.mged.org/mage-tab/tools.html], or create your own IDF and SDRF files based on the [Sourceforge MAGE-TAB documentation|http://tab2mage.sourceforge.net/docs/magetab_docs.html]. Be sure and review the details in [Appendix A - MAGE-TAB in caArray|https://wiki.nci.nih.gov/x/Rho9Ag] to ensure that your MAGE-TAB files meet the specifications for compatibility with caArray. For more information about when to use MAGE-TAB annotation files in caArray, refer to [caArray 008 - How do I use the Annotation Tab versus MAGE-TAB Annotation Files in caArray?|caArray 008 - Should I use the AnnotationAnnotations tab or MAGE-TAB annotation files to annotate my experiment?]. For more information on how to upload MAGE-TAB files, refer to [Importing MAGE_TAB Files|https://wiki.nci.nih.gov/x/Oxo9Ag#7-SubmittingDatatoanExperiment-ImportingMAGETABData] in the caArray User's Guide. h2.
