Figure 1.

Positional classification of the long non-coding RNAs (lncRNA). Carton displays the LncRNA (red) classification base on (a) the location between two coding genes (intronic, exonic, intergenic, or overlapping), (b) the template strand (sense, antisense), and (c) transcription direction when coding genes and lncRNA are transcribed in the same strand (divergent, convergent). Gray arrow indicates in which direction transcription is proceed. Green and blue boxes represent exons of two different genes.
