Group comparisons Definitions: The order of a comparison is important and is pre-defined by the order of the pairwise comparisons. Experiment Chips (EC) are compared to Baseline Chips (BC). If experiment chips present higher expression levels than baseline chips, the signal log ratio and the fold change values are positive, otherwise both are negative. You may not change this order, but you can always retrieve for decreased expression by using the negative values.
