H2AZ_EMT

Bash and R scripts associated with analysis of H2A.Z ChIP-Seq data from TGFb-induced EMT in MDCK cells. Pre-release.

some requirements and status of different pipeline stages

tools & binaries

  • snakemake [>4.0]
  • bowtie2 [>2.1]
  • cutadapt
  • samtools
  • deepTools
  • R/Bioconductor [>3.4]
  • picardTools
  • htseq

pipeline stages

  • cutadapt_subworkflow.py - OK
  • bowtie2_subworkflow.py - OK
  • bam_processing_subworkflow.py - OK
  • merge_replicates_subworkflow.py - seems OK?
  • deepTools_QC_subworkflow.py - OK

Workflow invocation

Following variables need to be set at the command line at time of invocation of the workflow:

  • ASSAY="<type of sequencing experiment, e.g. ChIP-Seq or RNA-Seq, relative to working dir>"
  • RUNID="<name of subdirectory containing sequencing data, e.g. ArrayExpress ID, relative to working dir>"
  • WORKFLOWDIR="<name of directory where snakemake files are stores, e.g. name of git repo, relative to user /home>"

Example snakemake command

snakemake --snakefile merge_replicates_subworkflow.py --configfile config.json --config ASSAY=ChIP-Seq RUNID=NB501086_0011_MNekrasov_MDCK_JCSMR_ChIPseq WORKFLOWDIR="/Development/JCSMR-Tremethick-Lab/" --jobs 32 -pr

Example directory structure

variables used: ASSAY="ChIP-Seq" RUNID="NB501086_0011_MNekrasov_MDCK_JCSMR_ChIPseq"
