Mouse microarray probes reannotation and lncRNA classification. (A) Microarray probes reannotation pipeline for lncRNA. (B) Overlap of lncRNAs identified from Agilent, Illumina and Affymetrix platforms. (C) Classification of lncRNAs into five classes: exonic sense, intronic sense, antisense, bidirectional and intergenic. (D) Bar chart showing the number of lncRNAs in each class for all identified lncRNAs.
