Llama: an online microarray linear analysis tool

We have developed a linear modelling tool for analysis of two-colour microarray data that utilises a per-spot linear model to estimate expression differences. Given the design of the experiment, the program combines all relevant data to provide the best estimate of a particular difference in expression between samples. It constructs multiple estimates based on several slides and combines them to get the most precise overall estimates of differential expression. Every effort has been made to make this tool accessible to biologists and it contains many user-friendly option
