An error supression and variant calling pipeline for Second-Generation sequencing data
Description
See the full wiki page for more information: http://produse.readthedocs.io/en/latest/
Installation
Dependencies
You will need to install the following before installing Dellingr:
3.7>python>=3.4
bwa>=0.7.0
samtools>=1.3.1
Dellingr will check these dependencies prior to running the pipeline
To install the Dellingr package run the following command:
Install using the Python Package Index (PyPI)
pip install Dellingr
Install from Github
git clone https://github.com/morinlab/Dellingr.git
cd Dellingr
python setup.py install
All required python dependencies will be installed during this step
Running Dellingr
The Analysis Pipeline: Very Quick Start
You can view more detailed instructions on the wiki
All parameters required to run ProDuSe can be viewed using the following:
dellingr run_dellingr -h
Alternatively, if you wish to run Dellingr without installing it, you can run DellingrPipeline.py
manually in a similar manner:
/path/to/Dellingr/DellingrPipeline.py -h
While these parameters can be specified individually, they can also be provided using a configuration file
To run the analysis pipeline you simply need to run the following command:
dellingr run_dellingr
-c /path/to/github/clone/etc/dellingr_config.ini
Alternatively:
/path/to/Dellingr/DellingrPipeline.py
-c /path/to/github/clone/etc/dellingr_config.ini
This will run the entire Dellingr pipeline on all samples specified in the sample_config.ini file, which can be found in etc/sample_config.ini
Results will be located in the following directory:
ls ./dellingr_analysis_directory
Helper Scripts
The Dellingr package is comprised of several stages to aid in the analysis of duplex sequencing data.
These stages can be be viewed by running the following:
dellingr -h
dellingr adapter_predict
If you need to confirm the expected adapter sequence of a sample you should run the following command:
dellingr adapter_predict -i input1.fastq input2.fastq
This tool will print a predicted adapter sequence based off of ACGT abundances at each position. It uses these observed abundances and finds the closest expected abundance for an IUPAC unambiguous or ambiguous base.
