Figure 1From: Gene selection with multiple ordering criteriaVolcano Plot for Colon Data set. Volcano plot for the 2000 genes from the colon cancer data. The x-axis is the fold-change value and y axis is - log10 p-value, based on 50,000 permutations. Using the absolute 2-fold change and p-value 0.001 as the threshold cutoff, forty five genes in the upper left and upper right are selected.Back to article page
