Featurecounts rpkm
WebSep 26, 2024 · Here you can find some example R code to compute the gene length given a GTF file (it computes GC content too, which you don't need). This uses one of a number of ways of computing gene length, in this case the length of the "union gene model". In this method, the non-duplicated exons for each gene are simply summed up ("non … WebNov 11, 2015 · A gene counts table and isoform counts table were generated by featureCounts and RSEM, respectively. RPKM is calculated by different approaches. For transcript-based approach, reads are first …

WebHi Tim, The featureCounts() function in Rsubread counts the number of reads mapped to genes or exons and returns a list which includes a read count matrix and annotation information. The returned list object can be easily transformed to a DGEList object which can then be fed into downstream expression analysis packages like edgeR or limma. WebApr 11, 2024 · The RPKM counts (reads per kilobase per million mapped) for these orthologs were then retrieved from the respective RNA-seq data. ... , FeatureCounts v1.6.2 60 was used. The read counts were then ...
WebRPKM-normalized counts table For example, in the table above, SampleA has a greater proportion of counts associated with XCR1 (5.5/1,000,000) than does sampleB (5.5/1,500,000) even though the RPKM count values are the same. WebSorted by: 1 It's very unlikely that "a RPKM analysis" is the right answer. Assuming you'd like to do differential expression, using tools like DESeq or EdgeR on the count table are likely to be a better thing to do. For reasons why RPKM is not a good approach, have a read of this answer. Share Improve this answer Follow
WebOct 11, 2016 · We often need to get the R/FPKM values from a RNAseq experiment, and I just used the rpkm () function in edgeR.
