Full Description

P3: Portable Proteomics Pipeline

Github: https://github.com/kristiyanto/P3
Dockerhub: https://hub.docker.com/r/kristiyanto/p3/

P3 is a docker container for mass-spectometry data pre-processing pipelines. The pipelines consist of protein identification (using MSGF+ tool developed by PNNL), and quantification (Bioconductor / MSnbase).

Demo

Input

The container takes mass-spectometry raw files (*.mzml, *.mzml.gz, *.mgf, *.mzxml, *.ms2, *.pkl) and a peptide sequences file (*.fasta). Folder must be mounted to the container's "/root/data" (e.g. using -v tag).
Click here for more information about Docker Volumes.

The files can be retrieved from a mounted local storage.

Alternatively, the container can also retrieve the files from the internet by providing either FTP address or PrideID in the p3.config file.

Configuration Files

If not provided, p3.config template will be created. The configuration file navigates how the pipeline should be run. Inspect p3.config before re-run.

Running the container

docker pull kristiyanto/p3
docker run --rm -v /path/to/files:/root/data kristiyanto/p3

# e.g: Windows
docker run --rm -v /c/Users/daniel/p3-data:/root/data kristiyanto/p3

#e.g: Mac/Linux
docker run --rm -v ~/Desktop/p3-data:/root/data kristiyanto/p3

Output

Once process is done, following files will be created:

  • *.txt : a tab delimited file of the result (spec-evalue, identified peptides, quantification results, etc.)
  • *.rda : R object of the results. Ensure MSnBase package is installed prior importing.
  • *.mzid : results from MSGF+

Requirements

To run P3, Docker engine must be installed. Click here for a detailed information to install Docker engine on various operating system including Windows and MacOS.

Protein identification and quantification is a computationally intensive process. Depending on the size of the data, at least 4Gb available memory on the Docker Machine is required.
