Bulk RNASeq analysis for differential expression

Bulk RNASeq analysis for differential expression

advanced bioinformatics
Location:

Leuven

Start date:

09 September 2019

Duration:

General context

  • We perform quality control of the sequence reads to detect biases or contamination
  • We map the reads to the reference genome using a transcriptome model.
  • We perform a detailed QC analysis of the mapping results to detect potential problems.
  • The mapping results are used to obtain transcript counts .
  • The count files are used to identify differentially expressed genes
  • We START a typical functional analysis of the obtained results in order to exemplify handy tools and commercial alternatives
Objectives

During this training you will:

  • execute a complete workflow at command line or in GenePattern to go from raw fastq files to count files
  • execute a complete workflow in R to detect differential expression between two conditions
  • initiate functional annotation and interpretation of the list of differentially expressed genes

 

Required skills

Familiarity with the Illumina sequencing process and with basic NGS data formats: FASTQ, SAM/BAM, GTF, ...If you do not meet these requirements you have to follow the "Introduction to the analysis of NGS data" training first.

Additionally you need to have experience in basic R programming. If you never worked in R you should attend the Basic statistics in R ​training first.
