=== 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. You can configure this by clicking the ''Add analysis'' tab in the main menu, then go to ''Configure datasets''.

* Analysis: the complete definition an an analysis, including data, parameters and function call.
* ''which 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'.
* ''which has multiple'' !DataNames: the 'types' of data used. For example: 'genotype' and 'phenotype'.
* ''which 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''.
