This program allows a user to determine what a normalization factor for an experiment would be, if only a subset of genes were used.

First you should enter either an experiment id or slidename, or select an arraylist in your home directory, to indicate which experiments you are interested in calculating a normalization factor for.

Next select a genelist which indicates which genes/spots on your arrays you wish to use for calculating the normalization value. You must also select the organism to which you genelist pertains.

Finally select the method by which you to use for additional spot selection criteria. Further help on how these methods work is available

After you hit the submit button, for each experiment a normalization factor will be calculated based on the normalization method you selected, and the genelist
