RNA-Seq sample
Load the RNA-Seq sample workflow into your current working directory.
library(systemPipeRdata)
genWorkenvir(workflow="rnaseq")
setwd("rnaseq")
Run workflow
Next, run the chosen sample workflow systemPipeRNAseq (PDF, Rnw) by executing from the command-line make -B within the rnaseq directory. Alternatively, one can run the code from the provided *.Rnw template file from within R interactively.
Workflow includes following steps:
- Read preprocessing
- Quality filtering (trimming)
- FASTQ quality report
- Alignments:
Tophat2(or any other RNA-Seq aligner) - Alignment stats
- Read counting
- Sample-wise correlation analysis
- Analysis of differentially expressed genes (DEGs)
- GO term enrichment analysis
- Gene-wise clustering
ChIP-Seq sample
Load the ChIP-Seq sample workflow into your current working directory.
library(systemPipeRdata)
genWorkenvir(workflow="chipseq")
setwd("chipseq")
Run workflow
Next, run the chosen sample workflow systemPipeChIPseq_single (PDF, Rnw) by executing from the command-line make -B within the chipseq directory. Alternatively, one can run the code from the provided *.Rnw template file from within R interactively.
Workflow includes following steps:
- Read preprocessing
- Quality filtering (trimming)
- FASTQ quality report
- Alignments:
Bowtie2orrsubread - Alignment stats
- Peak calling:
MACS2,BayesPeak - Peak annotation with genomic context
- Differential binding analysis
- GO term enrichment analysis
- Motif analysis
VAR-Seq sample
VAR-Seq workflow for single machine
Load the VAR-Seq sample workflow into your current working directory.

genWorkenvir(workflow="varseq")
setwd("varseq")
Run workflow
Next, run the chosen sample workflow systemPipeVARseq_single (PDF, Rnw) by executing from the command-line make -B within the varseq directory. Alternatively, one can run the code from the provided *.Rnw template file from within R interactively.
Workflow includes following steps:
- Read preprocessing
- Quality filtering (trimming)
- FASTQ quality report
- Alignments:
gsnap,bwa - Variant calling:
VariantTools,GATK,BCFtools - Variant filtering:
VariantToolsandVariantAnnotation - Variant annotation:
VariantAnnotation - Combine results from many samples
- Summary statistics of samples
VAR-Seq workflow for computer cluster
The workflow template provided for this step is called systemPipeVARseq.Rnw (PDF, Rnw).
It runs the above VAR-Seq workflow in parallel on multiple computer nodes of an HPC system using Torque as scheduler.
Ribo-Seq sample
Load the Ribo-Seq sample workflow into your current working directory.
library(systemPipeRdata)
genWorkenvir(workflow="riboseq")
setwd("riboseq")
Run workflow
Next, run the chosen sample workflow systemPipeRIBOseq (PDF, Rnw) by executing from the command-line make -B within the ribseq directory. Alternatively, one can run the code from the provided *.Rnw template file from within R interactively.
Workflow includes following steps:
- Read preprocessing
- Adaptor trimming and quality filtering
- FASTQ quality report
- Alignments:
Tophat2(or any other RNA-Seq aligner) - Alignment stats
- Compute read distribution across genomic features
- Adding custom features to workflow (e.g. uORFs)
- Genomic read coverage along transcripts
- Read counting
