LSTrAP
LSTrAP, short for Large Scale Transcriptome Analysis Pipeline, greatly facilitates the construction of co-expression networks from RNA-Seq data. The various tools involved are seamlessly connected and CPU-intensive steps are submitted to a computer cluster automatically.
Version 1.3 Changelog
- Support for PBS / Torque scheduler (note proper configuration is required)
- HISAT2 can be used as an alternative to BowTie2 and TopHat 2
- Added helper script to do PCA on samples
- Parameter names in data.ini changed, additional options added to config.ini. Check the configuration and update the files accordingly.
Workflow
LSTrAP wraps multiple existing tools into a single workflow. To use LSTrAP the following tools need to be installed
Steps in bold are submitted to a cluster. Optional steps can be enabled by adding the flag ‑‑enable‑interpro and/or ‑‑enable‑orthology.
Installation
Before installing make sure your system meets all requirements. A detailed list of supported systems and required software can be found here.
Use git to obtain a copy of the LSTrAP code
git clone https://github.molgen.mpg.de/proost/LSTrAP
Next, move into the directory and copy config.template.ini and data.template.ini
cd LSTrAP
cp config.template.ini config.ini
cp data.template.ini data.ini
Configure config.ini and data.ini using these guidelines
Running LSTrAP
Once properly configured for your system and data, LSTrAP can be run using a single simple command (that should be executed on the head node).
./run.py config.ini data.ini
Run using HISAT2
./run.py --use-hisat2 config.ini data.ini
Run with InterProScan and/or OrthoFinder
./run.py --enable-orthology --enable-interproscan config.ini data.ini
Furthermore, steps can be skipped (to avoid re-running steps unnecessarily). Use the command below for more info.
./run.py -h
