Introduction

There are many plug-ins in the Illumina plug-in package for BASE. This file gives detailed information on some of the contributed plug-ins.

Illumina detection P-value calculation

This plug-in implements BeadStudio like detection P-value calculations for Illumina expression data (see http://www.genomecenter.ucdavis.edu/expression_analysis/documents/GEX__normalization_070313.pdf on detection P-values.

The plug-in will always base the detection P-value calculation on raw data values, i.e., the mean raw intensity for the different bead types. However, only reporters included in the bioassay set will be included in the distributions. The effect of the reporter filtering that may have occurred is that if no negative control bead types are left in the bioassay set, there is no distribution of negative controls to base the P-value detection calculation on.

Hence, typically you should use the detection P-value plug-in before you remove the negative controls from your analysis.

There is a request, http://baseplugins.thep.lu.se/ticket/204, for an user selectable option to use all available negative controls in raw data even if no negative controls are left in a bioassay set.
