http://barc.wi.mit.edu/education/hot_topics/RNAseq_Feb2024/RNASeq_2024.pdf WebI have RNA-Seq data which is paired-end reads. Extracted the counts using featureCounts for all the samples. There is a function to convert counts to RPKM: using the gene_length rpkm <- function (counts, lengths) { rate <- counts / lengths rate / sum (counts) * 1e6 } I know that RPKM is mainly used for single-end reads data.

WebFor paired-end reads, use either FR or RF. We used 'R' argument for first-strand format FASTQ files, which means that our reads correspond to reverse complemented of transcripts. If our FASTQ files are second-strand format, then we should use 'F' argument instead of 'R' argument. -x argument: The basename of the index for the reference genome.
