For Linux and MacOS 🐧🍏

1. Create a Python environment named 'puma-env' or as per your preference.

   python3 -m venv puma-env
   

2. Activate the environment.

   source puma-env/bin/activate  # for Linux
   source puma-env/bin/activate  # for MacOS
   

3. Install PUMA 1.0.

   pip install pumaz
   

Congratulations! You're all set to start using PUMA 1.0.

For Windows 🪟

1. Create a Python environment, e.g., 'puma-env'.

   python -m venv puma-env
   

2. Activate the environment.

   .\puma-env\Scripts\activate
   

3. Install PUMA 1.0.

   pip install pumaz
   

You're now ready to experience the precision and speed of PUMA 1.0.

Usage Guide 📚

Start your journey with PUMA 1.0 by using our straightforward command-line tool. It requires the directory path containing different tracer images, and each image should be stored in separate folders. Here's how you can get started:

pumaz -d <path_to_image_dir>

Here <path_to_image_dir> refers to the parent directory containing different tracer images in their respective sub-directories.

For assistance or additional information, you can always type:

pumaz -h

Directory Structure and Naming Conventions for PUMA 📂🏷️

PUMA 1.0 requires your data to be structured in a certain way. It supports DICOM directories and NIFTI files. For NIFTI files, users need to ensure that the files are named with the correct modality tag at the start.

Required Directory Structure 🌳

Here is the directory structure that PUMA 1.0 expects:

Parent_Directory
│
└───Tracer1
│   │
│   └───PET_DICOM_Directory or PET_xxxx.nii.gz
│   │
│   └───CT_DICOM_Directory or CT_xxxx.nii.gz
│
└───Tracer2
│   │
│   └───PET_DICOM_Directory or PET_xxxx.nii.gz
│   │
│   └───CT_DICOM_Directory or CT_xxxx.nii.gz
...

└───Tracer3
    │
    └───PET_DICOM_Directory or PET_xxxx.nii.gz
    │
    └───CT_DICOM_Directory or CT_xxxx.nii.gz

Naming Conventions 🏷️

• For DICOM directories, no specific naming is required.
• For NIFTI files, the file should start with the modality tag (e.g., 'PET_' or 'CT_') followed by the desired name. For example, 'PET_MySample.nii.gz'.

Note: All the PET and CT images related to a tracer should be placed in the same directory named after the tracer.

A Note on QIMP Python Packages: The 'Z' Factor 📚🚀

All of our Python packages here at QIMP carry a special signature – a distinctive 'Z' at the end of their names. The 'Z' is more than just a letter to us; it's a symbol of our forward-thinking approach and commitment to continuous innovation.

Our PUMA package, for example, is named as 'pumaz', pronounced "puma-see". So, why 'Z'?

Well, in the world of mathematics and science, 'Z' often represents the unknown, the variable that's yet to be discovered, or the final destination in a series. We at QIMP believe in always pushing boundaries, venturing into uncharted territories, and staying on the cutting edge of technology. The 'Z' embodies this philosophy. It represents our constant quest to uncover what lies beyond the known, to explore the undiscovered, and to bring you the future of medical imaging.

Each time you see a 'Z' in one of our package names, be reminded of the spirit of exploration and discovery that drives our work. With QIMP, you're not just installing a package; you're joining us on a journey to the frontiers of medical image processing. Here's to exploring the 'Z' dimension together! 🚀
