Cross validation population size predictions for each tissue separately at CTSS, tag 
cluster, gene and ?dna-binding? gene levels. Each of the sub-directories holds 
corresponding four images. The figures for CTSS level cross validations are also 
shown in figure 2. 

The three different curves in each figure panel are top-down population size cut-offs 
1, 2 and 30. The vertical dashed bar indicates the size of the sample. To the left of 
the vertical bar is shown the 50% sub-sample cross validation predictions for ten 
repetitions. The three right subplots are zoom-in on the cross validation predictions. 
The red circle indicates the observed value in the sample and the squares show 95% 
posterior probability intervals.
