Comment: C: RNA-Seq analysis using STAR and Salmon
... There are a few conceptual issues that might help you in the analysis: 1. You said you aligned the reads with STAR to the UMD3.1 cattle genome. With such alignments you cannot quantify using salmon. To use Salmon you'll need to work with a transcriptome, available from here ftp://ftp.ensembl.org/pu ...
