A) ROC and B) PRC for predicting MPRA expression in mouse retina (Shen et al., 2016). Gkm-SVM trained on either retina ATAC-seq or DHS (dark red, red) predicts the expressing constructs with about 50% precision, but gkm-SVM trained on unrelated cell types does not (melanocytes, cyan; megakaryocytes, blue; lymphoblasts, green).
