WebApr 13, 2024 · All sequencing reads from RNA-seq were mapped to the porcine reference genome sequence (Sscrofa11.1) using hisat2-2.10. 50 FPKM (fragments per kilobase of exon per million fragments mapped) values were calculated by Cufflinks v.2.2.1 51 using default parameters for gene expression levels. WebHere we describe the method of analyzing RNA-seq data using the set of open source software programs of the Tuxedo suite: TopHat and Cufflinks. TopHat is designed to align RNA-seq reads to a reference genome, while Cufflinks assembles these mapped reads into possible transcripts and then generates a final transcriptome assembly.

WebMay 16, 2013 · A quick example of the technical aspect: assume a 1,000 bp transcript. experiment 1 is 5,000,000 total reads and this transcript received 5 hits. This calculates out to an FPKM of 1.0. But that FPKM is based on only 5 hits which is entirely unreliable. experiment 2 has 100,000,000 total reads and this transcript has 100 hits.
