Long non-coding RNAs (lncRNAs) are non-coding transcripts longer than 200 nucleotides.More and more studies have found that lncRNAs are very important for establishment and maintaining of chromatin interactions[1-3]which is closely with chromatin dynamics structures[5,7],chromatin modulation[6],transcription[8]and almost all of the molecuclar events happeded in nucleus.Therefore,its great interest to precdict and elucidate these lncRNAs which play critical roles in chromatin interactions.
