In figures 6D, 7 and S4 we have labeled the y-axis of the mRNA plots with 'RPKM'. This should be RPM instead.
In the methods subsection "mRNA read processing and mapping" the sentence "Coverage tracks were generated with deepTools v2.4.3 (bamCoverage–smoothLength 60 –binSize 20 –normalizeUsingRPKM) [75]" Should be replaced with: "Coverage tracks were generated with either deepTools v2.4.3 (bamCoverage–smoothLength 60 –binSize 20 –normalizeUsingRPKM) [75] to generate RPKM normalized tracks, or with Bedtools (genomeCoverageBed -bg -split -scale -ibam -g) [72], followed by bedGraphToBigWig, to summarize genome coverage normalized to mapped reads * 1 million (RPM)."
We, the authors, apologize for any inconvenience this may have caused.
