Getting Started

Installation

Installation proceeds as follows:

1. Fork and clone the nuremics-labs repository. You have two options to get started:

   • Option A (recommended): Fork the repo to your own GitHub or GitLab account, then clone your fork. This allows you to modify the code and push your changes to your personal version of the project.

         nuremics-labs  →  fork  →  your-labs  →  clone
     

   • Option B (quick start): If you just want to try the framework without making changes, you can simply clone the main repo directly.

     HTTPSSSH

     git clone https://github.com/nuremics/nuremics-labs.git
     

     git clone git@github.com:nuremics/nuremics-labs.git
     

2. (Optional, but recommended) Create the NUREMICS virtual environment. From the root directory of your cloned repo, use either conda or micromamba to create and install the environment using the provided environment.yml file.

   - Creation -

   CondaMicromamba

   conda create -f environment.yml
   

   micromamba create -f environment.yml
   

   - Activation -

   CondaMicromamba

   conda activate nrs-env
   

   micromamba activate nrs-env
   

3. Install NUREMICS with the demo application. Each application in nuremics-labs can be installed independently. You can start by installing the DEMO_APP.

   pip install .[DEMO_APP]
   

   This will install both the core nuremics framework and the nuremics-labs demo application.

Run the demo

To get hands-on experience with the NUREMICS framework, you'll start by running the DEMO_APP and reproducing the scientific results of the Study_Shape and Study_Velocity studies, as demonstrated in the video below.

When first run, a NUREMICS App creates a local workspace on your system, where you configure studies, set input data, and collect results. In this tutorial, instead of setting up from scratch, you'll start with a preconfigured workspace to reproduce the Study_Shape and Study_Velocity studies.

Follow these steps:

1. Download the NUREMICS_Starter archive. Retrieve the preconfigured NUREMICS_Starter archive and unzip it anywhere on your system.

   📦 Download NUREMICS_Starter archive

2. Prepare the NUREMICS working directory. Locate the nrs_working_dir folder inside the unzipped archive and move it to any location on your system that is most convenient for you.

3. Prepare the .nuremics directory. Locate the .nuremics folder in the same unzipped archive and place it at the root of your forked/cloned nuremics-labs repo.

4. Set the working directory for DEMO_APP. Edit the "working_dir" field in .nuremics/settings.json and set the full path to your local nrs_working_dir.

   📄 nuremics-labs/.nuremics/settings.json

   {
       "default_working_dir": null,
       "apps": {
           "DEMO_APP": {
               "working_dir": "path/to/your/nrs_working_dir",
               "studies": [
                   "Study_Shape",
                   "Study_Velocity"
               ]
           }
       }
   }
   

5. Run the DEMO_APP. From the nuremics-labs/src/labs/apps/general/DEMO_APP folder, run the App.

   python src/labs/apps/general/DEMO_APP/system.py
   

   This will launch both studies and store results in nrs_working_dir/DEMO_APP.

Play with it

Now that you've successfully run the DEMO_APP and reproduced the scientific results of the Study_Shape and Study_Velocity studies, let's play with it!

Skip a study

Want to skip the execution of a specific study when running your App? Set its "execute" field to false in the studies.json file.

📄 nrs_working_dir/DEMO_APP/studies.json

{
    "Study_Shape": {
        "execute": false,
        ...
    },
    "Study_Velocity": {
        "execute": true,
        ...
    }
}

Skip a process

Want to skip the execution of a specific process (Proc) within a study? Set its "execute" field to false in the process.json file.

📄 nrs_working_dir/DEMO_APP/Study_Velocity/process.json

{
    "PolygonGeometryProc": {
        "execute": false,
        "silent": false
    },
    "ProjectileModelProc": {
        "execute": true,
        "silent": false
    },
    "TrajectoryAnalysisProc": {
        "execute": true,
        "silent": false
    }
}

Silent a process

Want a specific process (Proc) to be executed in silent mode within a study? Set its "silent" field to true in the process.json file.

📄 nrs_working_dir/DEMO_APP/Study_Velocity/process.json

{
    "PolygonGeometryProc": {
        "execute": false,
        "silent": false
    },
    "ProjectileModelProc": {
        "execute": true,
        "silent": true
    },
    "TrajectoryAnalysisProc": {
        "execute": true,
        "silent": false
    }
}

Skip an experiment

Want to skip the execution of a specific experiment in a study? Set the value of the EXECUTE flag to 0 in the inputs.csv file for the experiment you want to skip.

📄 nrs_working_dir/DEMO_APP/Study_Velocity/inputs.csv

ID,EXECUTE
Test1,1
Test2,0
Test3,1

Run a new experiment

Want to run a new experiment in a study? Add a new line with a unique ID to the inputs.csv file.

📄 nrs_working_dir/DEMO_APP/Study_Velocity/inputs.csv

ID,EXECUTE
Test1,1
Test2,0
Test3,1
MyExp,1

Then run the App, which will automatically generate the corresponding input folder where you must upload the required velocity.json file.

📄 nrs_working_dir/DEMO_APP/Study_Velocity/0_inputs/0_datasets/MyExp/velocity.json

{
    "v0": 15.0,
    "angle": 60.0
}

Modify analysis settings

Want to customize the overall analysis of experiment results for a given study? Use the analysis.json file to control how each one is handled.
