Library source transcriptomic
Library selection cDNA
Instrument model Illumina NovaSeq 6000
 
Data processing Normal sequence Illumina Novaseq
Sequenced reads were trimmed for adaptor sequence, and masked for low-complexity or low-quality sequence, then mapped to mm10 whole genome using hisat2 v2.1.0 with parameters hisat2 -p 8 --dta -x -1 -2 -S.
Transcript assembly and quantification with StringTie. Analysis of RNA-seq experiments requires accurate reconstructions of all the isoforms expressed from each gene, as well as estimates of the relative abundance of those isoforms. Use parameters as stringtie –e –B -p 8 -G -o.
Fragments per kilobase of transcript per million mapped reads (FPKM) were calculated using Ballgown from Pertea M et al., Nature Protocols, 2016. In short, differential expression analysis proceeds using a linear model. The FPKM values attached to transcripts are typically highly skewed; thus, to stabilize the variance, Ballgown’s builtin functions apply a log transformation and then fit standard linear models that can be used to test for differential expression.
