xQTL workbench - Tag data and configure parameters ¶

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.
• 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 Tag data, found under Configure analysis. This presents you with an overview of matrices and possible tags, which can be applied in one click.
• Manually by using the menu Configure analysis. Select Configure datasets and configure Datanames and Datavalues.
