Microtest test data

Microtest is a repository of small test data from various data types, for testing pipelines.

Data descriptions

(please include here a short description of any data files you add)

• atac-seq_PE.bam: Random sample of paired-end ATAC-seq
• atac-seq_SE.bam: Random sample of single-end ATAC-seq
• bs_aln_k1k3.bam: Bisulfite data aligned to the methylated/unmethylated spike-in control sequences (k1/k3).
• chip-seq_PE.bam: Random sample of paired-end ChIP-seq
• chip-seq_SE.bam: Random sample of single-end ChIP-seq
• chipmentation_PE.bam: Random sample of paired-end ChIPmentation
• chipmentation_SE.bam: Random sample of single-end ChIPmentation
• dropseq_human.bam: Random sample of Drop-seq from human
• dropseq_mouse.bam: Random sample of Drop-seq from mouse
• hichip_PE.bam: Random sample of paired-end Hi-ChIP
• wgbs1.bam/wgbs2.bam: Random samples of unaligned WGBS data.

Usage

With looper/pypiper in a virtualev

# create and activate a virtual environment
virtualenv microtestenv; cd microtestenv; . ./bin/activate

# install the stack
pip install "peppy>=0.30.2,<1.0.0" "looper>=1.2.0,<2.0.0" "piper>=0.12.1,<1.0.0"

# clone open_pipelines and microtest
git clone https://github.com/epigen/open_pipelines
git clone https://github.com/epigen/microtest

# run
export CODE=`pwd`
# run only tutorial pipeline (no additional dependecies)
looper run microtest/config/microtest_config.yaml --sel-attr protocol --sel-incl Amplicon

# or run all (would require additional software dependecies)
# for now only ATAC-seq has been adapted
looper run microtest/config/microtest_config.yaml --sel-attr protocol --sel-incl ATAC-seq

Single pipeline usage

AMPLICON=`sed 's/,/\t/g' microtest/config/microtest_annotation.tutorial.csv | tail -n 1 | cut -f 14`
GUIDE=`sed 's/,/\t/g' microtest/config/microtest_annotation.tutorial.csv | tail -n 1 | cut -f 15`

python \
	open_pipelines/pipelines/amplicon_simple.py \
	-S microtest_amplicon \
	-i microtest/data/amplicon.fastq.gz \
	-g $GUIDE \
	-a $AMPLICON \
	-O microtest_amplicon

Automatic testing with a Github hook

1. Open a listening port for webhooks:
   1. Get ngrok at https://ngrok.com and open a port: ./ngrok 3456
   2. add that URL + "/payload" to the github webhook with a secret key
2. Create a listening server:
   1. git clone git@github.com:afrendeiro/github-webhook-handler.git
   2. modify github-webhook-handler/repos.json with your repositories that should trigger the testing and the secret key(s)
   3. start the server and leave it running: python github-webhook-handler/index.py 4567

When there is a push to your repositories, run_microtest.sh will run. This creates an isolated virtual environment, installs dependencies (not pipeline-specific ones though!) and runs the pipelines on the microtest data (similar to the example above).
