Flow chart of intergenic and intronic lncRNA identification and these length/exonic density. a Flow chart of intergenic/intronic lncRNAs and novel protein-coding gene identification analysis. RNA-seq data sets were assembled and merged into a transcriptome by Cufflinks. CPC score, protein domain and length were used to set inclusion and exclusion criteria for screening intergenic/intronic lncRNAs and putative protein-coding RNAs among the candidate unannotated transcripts. b Density plot of lengths for lncRNAs (blue) and coding RNAs (red). c Density plot of exons per transcript for lncRNAs (blue) and coding RNAs (red)
