snakePipes

snakePipes are flexible and powerful workflows built using Snakemake that simplify the analysis of NGS data.

Workflows available

DNA-mapping*
ChIP-seq*
mRNA-seq*
noncoding-RNA-seq*
ATAC-seq*
scRNA-seq
Hi-C
Whole Genome Bisulfite Seq/WGBS

(*Also available in "allele-specific" mode)

Installation

Snakepipes is a set of Snakemake workflows which use conda for installation and dependency resolution, so you will need to install conda first.

Afterward, simply run the following:

conda install mamba -c conda-forge && mamba create -n snakePipes -c mpi-ie -c bioconda -c conda-forge snakePipes

This will create a new conda environment called "snakePipes" into which snakePipes is installed. You will then need to create the conda environments needed by the various workflows. To facilitate this we provide the snakePipes commands:

conda activate snakePipes to activate the appropriate conda environment.
snakePipes createEnvs to create the various environments.

Indices and annotations needed to run the workflows could be created by a simple command :

createIndices --genomeURL <path/url to your genome fasta> --gtfURL <path/url to genes.gtf> -o <output_dir> <name>

where name refers to the name/id of your genome (specify as you wish).

A few additional steps you can then take:

1. Modify/remove/add the organism yaml files appropriately : these yaml files would contain location of appropriate GTF files and genome indexes corresponding to different organisms. The location of these files after installation can be found using snakePipes info command.

2. Modify the cluster.yaml file appropriately : This yaml file contains settings for your cluster scheduler (SGE/slurm). Location revealed using snakePipes info command.
