Hisat2 + featurecounts
Webb2 aug. 2024 · Although the primary purpose of RNA-seq is to quantify the expression level of known genes, RNA variants are also identifiable. However, care must be taken to account for RNA’s dynamic nature. In this study, we evaluated the following popular splice-aware alignment algorithms in the context of RNA variant-calling analysis: HISAT2, … WebbHISAT2 graph-based alignment of next generation sequencing reads to a population of genomes HISAT2 is a fast and sensitive alignment program for mapping next-generation sequencing reads (both DNA and RNA) to …

Did you know?
WebbHISAT2 is a fast and sensitive alignment program for mapping next-generation sequencing reads (both DNA and RNA) to a population of human genomes as well as to a single reference genome. Webb8 maj 2024 · aligning or mapping the quality-filtered sequenced reads to respective genome (e.g. HISAT2 or STAR). You can read my article on how to map RNA-seq reads using STAR. quantifying reads that are mapped to genes or transcripts (e.g. featureCounts, RSEM, HTseq) Raw integer read counts (un-normalized) are then used …
Webb10 apr. 2024 · Instead, several splice-aware mappers (e.g., TopHat , HISAT2 [13, 14], STAR ) have been developed to efficiently map transcript-derived reads against a reference genome. Here we will map our reads to the D. melanogaster genome using STAR. Hands ... FeatureCounts can also generate a file with the length of each gene, ... WebbfeatureCounts requires gene annotation specifying the genomic start and end position of each exon of each gene. Rsubread contains built-in gene annotation for mouse and human. For other species, users will need to read in a data frame in GTF format to define the genes and exons. Users can also specify a custom annotation file in SAF format.
WebbThe HISAT2-featureCounts-edgeR pipeline is therefore the best of the five pipelines used because it takes a short time, the quantification method (the read count) is the simplest and fastest, and the differential analysis gives the best results, with a low number of potential false positives. Figure 3. Workflow of HISAT2-featureCounts-edgeR ... 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.
