Corrigendum: Ab initio reconstruction of cell type–specific transcriptomes in mouse reveals the conserved multi-exonic structure of lincRNAs

In the version of this article initially published, the fourth sentence in the Online Methods section “RNA extraction and library preparation,” that read in part “procedure that combines a random priming step with a shearing step8,9,28 and results in fragments of ~700 bp in size,” should have read, “procedure that combines fragmentation of mRNA to a peak size of ~750 nucleotides by heating6 followed by random-primed reverse transcription8.” The error has been corrected in the HTML and PDF versions of the article.
