Bulk RNASeq: from counts to differential expression
2 days
General context
The course consists of introductory online material (e-learning) on counting and two face-to-face sessions on differential expression analysis in R and all the questions that arise when trying the analysis on your own data.
------------------------------------------------------------------------------------------------------------------------------
The course will show:
- Tools to generate count files like featureCounts, and htseq count are demonstrated
- Count files from HTSeq-Count, FeatureCounts, Salmon or Kallisto are used to identify differentially expressed genes
On the second day, participants can analyze their own count files. Issues are solved and questions are answered by experts from the VIB Nucleomics Core.
Knowledge of NGS data formats and the first steps in the analysis workflow (fastqc -> bam files). If you are a newbie in the field, you have to follow the NGS introduction training first.
Experience in R programming. If you never worked in R you should attend the R introduction training first.
- Counting using Galaxy: STAR, htseq-counts, FeatureCounts
- Identification of DE using Bioconductor: DESeq2 + other packages like tximeta (script for EdgeR is provided but not demonstrated)
- Visualization of results using R: ggplot2, pheatmap,
- Mapping of IDs to Gene symbols using Bioconductor: AnnotationDbi
Trainers
Janick Mathys
Janick tries to help VIB scientists analyze their data by offering bioinformatics training and support. Next to organizing trainings, creating e-learning courses and teaching statistics, R, Python, Linux, HPC, bulk and single cell RNA-Seq analysis, she consults scientists and develops pipelines for omics analyses. Before joining VIB, she worked as a post-doc at KULeuven, doing research on transcriptomics and transcription regulation. She coordinated the Master of Bioinformatics program of KULeuven and taught the course on Biological Databases.

Leuven - Campus Gasthuisberg
Leuven train station is approximately 4 km from the campus Gasthuisberg. Buses depart very regularly to the Gasthuisberg Campus from Leuven train station.
For tickets and up to date schedules visit website De Lijn or use the De Lijn App.
Exit at the very last bus stop ‘Gasthuisberg Campus) make sure not to exit at ‘Gasthuisberg Kliniek =
hospital)
Once you get off the bus, go to your right and go up the street until you see stairs to your left. Climb the stairs all the way up between two buildings. Look for the signs containing blue circles and white numbers and follow them all the way from 2 up to number 12. You will cross several buildings and the walk will take max. 10 minutes. When you reach number 12, you have reached O&N 5, where you can find the reception.

Leuven - Campus Gasthuisberg
The Gasthuisberg campus is west of the Leuven ring. Our buildings are situated behind the hospital (see black arrow near ‘RING NOORD’ on the map). If you come from the city center, you will arrive on campus from the east side (taking Mgr. Van Waeyenberglaan and roundabout Het Teken). If you come from Heverlee or Campus Arenberg, you will arrive from the west side (taking the Celestijnenlaan and Taborweg). When you arrive uphill at the intersection with the Rega Institute and the Red Cross building, you need to take the road down to the bicycle parking at Rega Institute (see map) where you can park. Next, follow the ‘Onderwijs & Navorsing blue route’ description below (start point is #9).

Leuven - Campus Gasthuisberg
You arrive via the E314 highway – EXIT 16
After 200 m, keep left to drive underneath the roundabout and into the tunnel.
Keep left and follow the arrows to Parking West.
You arrive via the Leuven ring road
At the roundabout, take the exit towards ‘Spoed / Ziekenhuis’.
Follow the ring around Campus Gasthuisberg and pass the entrance of SPOED.
Continue right until you arrive at a second roundabout.
Follow the directions for E314.
Near the Fire Brigade Station, make a U-turn and follow the directions for ‘Ziekenhuis’.
Keep left and drive downhill, underneath the roundabout and into the tunnel.
Keep left and follow the arrows to Parking West.
Next, leave the parking at level +1 using the big stairs near the vending machines.
Follow the red carpet and arrows to 'Onco Dagcentrum' to get to the O&N buildings. Take the stairs on your left after exiting Parking West. You are now in front of the O&N4 building; on the left you will find O&N5.
