This is maintained, and should work, but is deprecated in favor of https://github.com/hbc/bcbioRNASeq for most use cases
This repository generates a Rmarkdown report from a bcbio-nextgen RNA-seq run. The report isn't a finalized analysis and definitely needs a trained person with exerpience to interpret and tweak it, but it does a lot of the annoying plumbing work when setting up an analysis. It generates a large amount of useful quality control information, runs a differential expression analysis with DESeq2 and sets up using Sleuth or doing a pathway analysis if those options are flagged on.
Conda install (UNIX only)
conda install -c bioconda bcbio-rnaseq
git clone https://github.com/roryk/bcbio.rnaseq
- Install the necessary libraries
cd bcbio.rnaseq Rscript resources/scripts/install_libraries.R
- Make an executable.
This will make an executable in
bin/bcbio-rnaseq that you can move to wherever
you want and run.
Generating a bcbio-nextgen report
This produces a Rmd file with a report of a bcbio-nextgen run. If you run it without passing a formula, it will just generate a quality-control report. If you pass a formula like this:
bcbio-rnaseq summarize path-to-project-summary-yaml -f "~batch+panel"
It will run a DESeq2 analysis with the specified model and prepare reports of all pairwise comparisons for the last factor in the model. An example report is available here.
Other options you can pass are
--sleuth which will set up a
sleuth object to perform transcript
level differential expression. Passing the
--organism parameter with either
human will set up functions to run clusterProfiler GSEA and gene
enrichment analyses using the results of DESeq2 objects.
