Salmon exposes many different options to the user that enable extra features or modify default behavior. Long-Read Sequencing of Chicken Transcripts and Identification of New Transcript Isoforms. In order to quantify transcript-level abundances, Salmon requires a target transcriptome. We acquired the raw counts dataset split into the individual eight samples from the ExperimentHub R package, as described here. In the CK vs. LC10, LC30, and LC50 groups, among the top 20 enriched pathways (, Analysis of the first 20 pathways enriched in the DET sets between the different treatment groups revealed three common pathways (, In total, 56 differentially expressed P450-related transcripts were obtained from multiple sets of differentially expressed transcripts. To perform sample-level differential expression analysis, we need to generate sample-level metadata. ; Kitamoto, T.; Geyer, P.K. One aliquot of PBMCs was activated by 100 U/mL of recombinant IFN- for 6 hours. Some of the R helper scripts require a csv version of this, where the columns are separated by comma. ; Wang, J.Y.

A useful initial step in an RNA-seq analysis is to assess overall similarity between samples: To explore the similarity of our samples, we will be performing sample-level QC using Principal Component Analysis (PCA) and hierarchical clustering methods. ; Wang, Y.Z.

NOTE: The DESeq2 vignette suggests large datasets (100s of samples) to use the variance-stabilizing transformation (vst) instead of rlog for transformation of the counts, since the rlog function might take too long to run and the vst() function is faster with similar properties to rlog. Expression responses of nine cytochrome P450 genes to xenobiotics in the cotton bollworm. ; et al.

Differential expression analysis with DESeq2 involves multiple steps as displayed in the flowchart below in blue. Generally, we would recommend a more stringent and hands-on exploration of the quality control metrics and more nuanced picking of filtering thresholds, as detailed here; however, to proceed more quickly to the differential expression analysis, we are only going to remove count outliers and low count genes using functions from the scater package as performed in the Bioconductor tutorial.
