WellInverter is a web application developed in the Ibis group. It implements linear inversion methods for the reconstruction of gene expression profiles from fluorescent or luminescent reporter gene data.
As input, WellInverter reads the primary data file produced by a multi-well microplate reader, containing time-series measurements of the absorbance (optical density) as well as the fluorescence and luminescence levels in each well (if available). Various modules exist to analyze the data, in particular for detecting outliers, subtracting background, estimating growth rates, promoter activities and protein concentrations, visualizing expression profiles, computing statistics on replicate profiles, etc.
WellInverter uses a plug-in system for defining high-level routines for parsing different types of primary data files. Parsers for Tecan and Perkin-Elmer microplate readers are currently available.
