The purpose of this repo is to provide a starting point for other software that uses PETSIRD.

The Emission Tomography Standardization Initiative (ETSI) is working towards establishing a standard for PET Raw Data, called PETSIRD ("PET ETSI Raw Data").

The specification uses the yardl tool to define the model. yardl can be used to read the specification (in the model directory) and generate an PI for both C++ and API to read/write PETSIRD data.

Currently, a draft model is defined in https://github.com/ETSInitiative/PRDdefinition.

CAVEAT: the draft model generates code in the prd namespace. Nevertheless, we have used the name PETSIRD here in most places (except where needed).

These instructions will use YourRepoName for the name of your new repository. Obviously replace it with something appropriate.

Easiest is to start from GitHub:

1. Navigate to the URL of this repo: https://github.com/ETSInitiative/PETSIRDUseCaseTemplate
2. Click on the Use this template button and create your own repo
3. Pull it to your own local machine and modify
   1. Search-and-replace all occurences of PETSIRDUseCaseTemplate with YourRepoName
   2. Update the README.md to remove references to this template and write something about what your repo is going to do
   3. Update the environment.ymlto include what you need. For instance, if you need ROOT, add something like - root=6.28.0
   4. Make some other basic changes and commit

      git commit -a -m "Updated template to YourRepoName"
      git push

1. Open your repo in GitHub Codespaces or in a VS Code devcontainer. This codespace/container will contain all necessary tools, including yardl itself, as well as your repository.
2. Use yardl to generate C++ and Python code for the model:

cd YourRepoName
cd PETSIRD/model
yardl generate
cd ../..

3. Start working in either the cpp and/or python directories.
