=== What is tagging ===

Data matrices must be linked to an analysis before they can be selected when starting to run this analysis. This happens in the ''!DataSet'' part of the analysis.

* Analysis: the complete definition an an analysis, including data, parameters and function call.
* ''has one'' !DataSet: the wrapper for a set of data which can be used in this analysis. (can be shared across analyses) For example: 'Rqtl_data'.
* ''has multiple'' !DataNames: the 'types' of data used. For example: 'genotype' and 'phenotype'.
* ''has multiple'' !DataValues: the cross references to datamatrices which are applicable to this type of data. For example, for 'genotype' -> 'bxd_geno', "bxd_geno_corrected", "yeast_geno_2011", "mygenotypes", etc.

=== How do you tag ===

* Automatically through the ''Import Data'' plugin in the case of QTL data. An uploaded phenotype matrix named 'humanGeno' is tagged as 'Rqtl_data' -> 'genotype' -> 'humanGeno'.
* Easily with a helper plugin called ''Matrix wizard''. Found under ''Settings'', click ''Utilities''. This presents you with an overview of matrices and possible tags, which can be applied in one click.
* Manually by using the menu ''Add analysis''. Select ''Configure datasets'' and configure ''Datanames'' and ''Datavalues''.
