Screening and classification of the candidate lncRNAs in chicken trachea transcriptome. a Venn diagrams of coding potential analysis according to strict criteria. Four tools (CPC, CNCI, PFAM, and PhyloCSF) were used to analyze the coding potential of lncRNAs. Those simultaneously shared by four analytical tools were designated as candidate lncRNAs and used in subsequent analyses. b Classification of the two subtypes of lncRNAs
