What PiGx can do for you

What is PiGx?

PiGx is a collection of genomics pipelines. More information can be found in PiGx website

It includes the following pipelines:

  • PiGx BSseq for raw
    fastq read data of bisulfite experiments

  • PiGx RNAseq for RNAseq samples

  • PiGx scRNAseq for
    single cell dropseq analysis

  • PiGx ChIPseq for
    reads from ChIPseq experiments

  • PiGx CRISPR (work in progress)
    for the analysis of sequence mutations in CRISPR-CAS9 targeted
    amplicon sequencing data

All pipelines are easily configured with a sample sheet (in CSV
format) and a descriptive settings file (in YAML format). For more
detailed information see the README.md file for each of the pipelines
in the pipelines directory.

Getting started

To run PiGx on your experimental data, describe your samples in a CSV
file sample_sheet.csv, provide a settings.yaml to override the
defaults defaults, and select the pipeline.

To generate a settings file template for any pipeline:

pigx [pipeline] --init=settings

To generate a sample sheet template for any pipeline:

pigx [pipeline] --init=sample-sheet

Here's a simple example to run the RNAseq pipeline:

pigx rnaseq my-sample-sheet.csv --settings my-settings.yaml

To see all available options run pigx --help.

Install

Pre-built binaries for PiGx are available through GNU Guix, the
functional package manager for reproducible, user-controlled software
management. Install the complete pipeline bundle with the following
command:

guix install pigx

If you want to install PiGx from source, please make sure that all
required dependencies are installed and then follow the common GNU
build system steps after unpacking the latest release
tarball
:

./configure --prefix=/some/where
make install

You can enable or disable each of the pipelines with the
--enable-PIPELINE and --disable-PIPELINE arguments to the
configure script. PIPELINE is one of bsseq, rnaseq,
scrnaseq, chipseq, and crispr. For more options run
./configure --help.
