Figure 4From: Methods for estimating human endogenous retrovirus activities from EST databasesCorrelation between estimated age and activity. Estimated age vs. activity (EST count) plot for all HERVs. HERVs with unknown age are plotted separately on the left (random jitter has been added in the age direction). We can see that there is no clear correlation between estimated age and activity. There is a more detailed figure in the Additional file 1.Back to article page
