PMACE is a framework for distributed reconstruction such as ptychographic image reconstruction.

This python package implements PMACE approach in python.

1. Download the source code:

   Move to a directory of your choice and run the following commands.

   git clone https://github.com/cabouman/ptycho_pmace.git
   cd ptycho_pmace

2. Installation:

   It is recommended that you install the package to a virtual environment. Install Anaconda and follow any of the two methods.

• 2.1. Easy installation: If you have Anaconda installed, run the following commands.

  cd dev_scripts
  source ./clean_install_all.sh
  cd ..

• 2.2. Manual installation: Note the pmace environment needs to be activated every time you use the package.

  • 2.2.1 Create a Virtual Environment:

    conda create --name pmace python=3.8
    conda activate pmace

  • 2.2.2 Install the dependencies:

    pip install -r requirements.txt

  • 2.2.3 Install the package:

    pip install .

  • 2.2.4 Install the documentation:
