Detection of spurious genes.

<p><i>RPE:</i> the number of Reads Per Exon after adjusting the length of the exon and the overall sequencing depth per sample. <i>P_HQR</i>: the Proportion of High-Quality Reads for each exon. Each point represents an exon. The grey points represent all the exons in one sample. The red points indicate the distribution of the 13^th exon of the gene <i>CDC27</i> in all 36 samples, and purple points indicate the distribution of the 42^nd exon of the gene <i>MLL3</i> in all 36 samples, both of which are representative spurious genes and failed to be validated by experiments. The vertical dash line is set <i>RPE</i> = 1.5 and the horizontal dash line is set <i>P_HQR</i> = 0.4.
