Figure 4

The spermatocyte model achieves comparable performance to microarray expression of male germ cell isolates. Precision-recall curves were plotted to evaluate the method performance on classifying training data. The curve of the spermatocyte model in Figure 2A is displayed here again for comparison. A. Expression levels of isolated spermatogonia and pachytene spermatocytes from [12, 20]. Training genes were sorted in descending order of log2 expression, and precision and recall were calculated with a log2 expression decrement of 2. B. Expression levels of isolated spermatogonia and pachytene spermatocytes from [7]. Training genes were sorted in descending order of log2 expression, and precision and recall were calculated with a log2 expression decrement of 2.
