Hisat2 + featurecounts

WebbIn addition to using one global GFM index that represents a population of human genomes, HISAT2 uses a large set of small GFM indexes that collectively cover the whole genome (each index representing a genomic region of 56 Kbp, with 55,000 indexes needed to cover the human population). WebbHISAT2 is a fast and sensitive alignment program for mapping next-generation sequencing reads (whole-genome, transcriptome, and exome sequencing data) against the general …

Webb17 aug. 2016 · A quick look at a single simulation indicated that the featureCounts method underestimates the abundance of genes with less than 90% unique sequence which is exactly what we’d expect as reads which could be assigned to multiple genes will be ignored. See Figure 2-5 for a comparison with salmon. Figure 2. WebbI used HISAT2 to align more RNAseq fastq files and then featureCounts to count my features. All my mRNA counts look as expected but I want to count rRNA as well, however, it is saying 0 counts for rRNA even though I did not do rRNA depletion. I really want to know my rRNA counts.
