Overview

Requirements

  • Kallisto : expression quantification

  • R

    • packages: tidyverse, jsonlite

  • Need to have a config.yaml in your project directory:

rootdir: $HOME/mage-pipeline
projdir: /home/ubuntu/mage-user
metafile: meta.txt
gtffile: /home/ubuntu/mage-user/ref/Macaca_mulatta.Mmul_8.0.1.90.gtf
reffasta: /home/ubuntu/mage-user/ref/Macaca_mulatta.Mmul_8.0.1.cdna.all.fa
refindex: /home/ubuntu/mage-user/ref/Macaca_mulatta.Mmul_8.0.1.cdna.all.kallisto_v0.43.0.idx
kallisto: ~/bin/kallisto_linux-v0.43.0/kallisto

Setup

cd mage-pipeline
source setup.sh

Provide the id for each samples

meta.fastq.txt

src/utils/dir2meta.shi can be used to make the meta file

Quantification

Input for quantification

  • GTF file
  • Fastq file
  • Kallisto index

tar xzvf kallisto_linux-v0.43.1.tar.gz

Creating a Kallisto index

~/bin/kallisto_linux-v0.43.1/kallisto index --index=Macaca_mulatta.Mmul_8.0.1.cdna.all.idx Macaca_mulatta.Mmul_8.0.1.cdna.all.fa

Installing go

Go packages

go get github.com/urfave/cli
go get gopkg.in/yaml.v2

Implementation notes

mage-quant creates quant.ok in the kallisto output directory to indicate everything run well
