Relationship between the RPK expression levels and gene model characteristics.

The traces represent the total number of gene models expressed (blue line) at or above some minimum RPK (log scale), the number of models in the subset of expressed genes that have at least one detectable internal sequence deviation (red line), and total number of expressed models that still contain at least one detectable internal sequence deviation after attempts were made to bridge those flags with the set of expressed RNAseq data (green line).
