An introduction to RNA-Seq

Objective for the practical

• To learn about how to process, analyse and interpret RNA-Seq data

Learning goals

• Experience using the Linux operating system (Ubuntu)
• Learn how to run bioinformatics tools on the command line
• Learn how to use R and R-studio
• Visualise sequencing alignments in a genome browser
