Expression Genotype. An instance of a PM/MM ratio data file from adenocarcinoma positive sample-replicates loaded into the heat-map viewer for expression signature pattern analysis. Removal of unchanging probes from the expression signature pattern and tuning of an equivalency parameter (E) to adjust for measurement precision differences leaves a dataset that can be classed as A [PM/MM < (1.0 - E)], class B [PM/MM > (1.0 + E)] or class A/B [PM/MM between (1.0 ± E) inclusive]. On the right, the table shows the data state as it goes through expression signature pattern steps.
