PyProphet: Semi-supervised learning and scoring of OpenSWATH results.

PyProphet: Semi-supervised learning and scoring of OpenSWATH results.

PyProphet is a Python re-implementation of the mProphet algorithm [1] optimized for SWATH-MS data acquired by data-independent acquisition (DIA). The algorithm was originally published in [2] and has since been extended to support new data types and analysis modes [3,4].

Please consult the OpenSWATH website for usage instructions and help.

Installation

Option 1: Python Package Index (PyPI)

Install the stable version of pyprophet from the PyPI:

    $ pip install pyprophet

Option 2: Pre-built Executables (No Python Required)

Download from GitHub Releases:

• Linux:
• Windows:
• macOS Intel:
• macOS Apple Silicon:

Option 3: From Source

We strongly advise to install PyProphet in a Python virtualenv. PyProphet is compatible with Python 3.

Install the development version of pyprophet from GitHub:

    $ git clone https://github.com/pyprophet/pyprophet.git
    $ cd pyprophet  
    $ pip install . 

or

    $ pip install git+https://github.com/PyProphet/pyprophet.git@master

Option 4: Docker / Singularity

PyProphet is also available from Docker (automated builds):

Pull the latest version of pyprophet from DockerHub or Github Container Registry (synced with releases):

    # Dockerhub
    $ docker pull pyprophet/pyprophet:latest

    # Github Container Registry
    $ docker pull ghcr.io/pyprophet/pyprophet:latest

    # Singularity image
    $ singularity pull pyprophet.sif oras://ghcr.io/pyprophet/pyprophet-sif:latest

Running pyprophet

pyprophet is not only a Python package, but also a command line tool:

   $ pyprophet --help

or:

   $ pyprophet score --in=tests/test_data.txt

Documentation

API and CLI documentation is available on Read the Docs.

Running tests

The pyprophet tests are best executed using py.test and the pytest-regtest plugin:

    $ pip install pytest
    $ pip install pytest-regtest
    $ py.test -n auto ./tests
