ROC curve for Bi-peak shape identification. According to the distance between paired genes, 5 categories of bi-peak shapes and single peak shapes simulated from expressed genes and unexpressed genes are presented in different color. The bi-peak shapes and single peak shapes were considered positive and negative sets, respectively. The ROC curve was generated using ROCR library in the R project http://www.r-project.org webcite.
