RPolII signal, CSF scores, expression levels and conservation in lincRNA regions. (a) The RNA polymerase II ChIP-seq signals in protein coding genes, lincRNA regions, and randomly selected regions. The RPolII signal is demonstrated as reads per kilobase exon model per million mappable reads. (b) The CSF score of the lincRNA regions, protein-coding genes, and randomly selected regions. (c) The RPKM values for the exonic and intronic regions for both lincRNAs and protein-coding genes. (d) Conservation levels for exonic regions, intronic regions for both lincRNAs and protein-coding genes. X axis denotes the conservation score $\omega$ derived from Siphy prediction. A smaller and larger $\omega$ value indicates more and less conserved, respectively.
