Spot shape models source code for R

This page contains the source code for R to model the shape of cDNA microarray spots. The reference for the functions can be found in the paper Spot shape modelling and data transformations for microarrays. published in Bioinformatics. Functions will be documented shortly.

Functions for creating table 1

Functions for creating table 2


This section contains the source code for R related to spatial correlated spot shape models. The reference is in the soon-to-be-published paper Pixel-level Signal Modelling with Spatial Correlation for Two-Colour Microarrays. Functions will be documented shortly.

Fucntion for doing the approximation with the conditional expectation


The R-code above use my microarray package for R to read tiff files and extract the necessary spot areas. The microarray package is very much under construction but you are more than welcome to download it and use it. It requires the libtiff library to compile and at least it works under linux - I haven't tried any other OS. Before downloading you may want to read the documentation (in PDF).

As always ... please let me know of any bugs, comments and suggestions for the package.
