You can select older versions with `--dataset_id [ID]`

All spine segmentation models for VIBE, CT and T2w have been moved to [SPINEPS](https://github.com/Hendrik-code/spineps)

¹ Use run_water_fat_swap_detection.py; If you only want the swaps segmented, else look in the other repo

All outdated/deprecated models are still available, we just no longer recommend them, as their should be better alternatives.

## Installation Guide

### System Requirements
- Python 3.9 or higher.
- Tested on Ubuntu and Windows.
- One of the following:
  - Nvidia-GPU with 8 GB of RAM or more.
  - A mps device (--ddevice mps)
  - A strong CPU; This is usually very slow. (--ddevice cpu)

### Installation Guide

1. Open a command line (search for Terminal on Mac or cmd on Windows in your OS search).
2. Ensure you have Anaconda (Python) installed.
3. Navigate to the folder where you want to download the script using `cd [FOLDER PATH]`.

```bash
# Run this commands by coping in to the Terminal
# Recommended: make a virtual Python environment (example shows Anaconda)
conda create -n "VIBESegmentator" python=3.11.0
conda activate VIBESegmentator

# Install PyTorch that works with your GPU (follow instructions at https://pytorch.org/get-started/locally/)
pip install torch torchvision torchaudio

# Install required Python packages
pip install TPTBox ruamel.yaml configargparse
pip install nnunetv2 
# We recommend the newest versions. Tested versions: TPTBox==1.6, ruamel.yaml==0.18.6, configargparse==1.7, nnunetv2==2.4.2

# If e. g. nnunetv2 does not work, try version 2.4.2
# Uninstall the current version and reinstall with the specified version
#pip uninstall nnunetv2
#pip install nnunetv2==2.4.2

# Download the scripts (they will be downloaded to your current folder)
git clone https://github.com/robert-graf/VIBESegmentator.git
cd VIBESegmentator
```
It should take less than 30 minutes to install, excluding installing conda/python. The longest time takes to install pytroch. 
## Download

Download the nnUNet weights automatically. They are put in `[Path to this project]/nnUNet/nnUNet_results/`.

## Run
```bash
# Run this commands in a Terminal where you navigate to the folder where `run_VIBESegmentator.py` is
conda activate VIBESegmentator

# Total Segmentation
python run_VIBESegmentator.py --img [IMAGE-PATH] --out_path [OUTPATH] --ddevice [cpu|cuda|mpu (optional)]

```

### Running an Example
```bash
conda activate VIBESegmentator
#cd to the folder where you downloaded the GitHub files (the folder where the run_VIBESegmentator.py is located)
```
Let's run some examples that were never seen during training. You can download all four examples from [here](https://github.com/robert-graf/VIBESegmentator/releases/download/example/example_mri.zip)

(Source: [link](https://zenodo.org/records/11367005) Number s0284, s0286, s0287, s0288)

Unzip the file. For this example, we copied all files to a folder called 'example' where the run_VIBESegmentator.py is located.
```bash

python run_VIBESegmentator.py --img example/mri1.nii.gz --out_path  example/seg1.nii.gz

python run_VIBESegmentator.py --img example/mri2.nii.gz --out_path  example/seg2.nii.gz

python run_VIBESegmentator.py --img example/mri3.nii.gz --out_path  example/seg3.nii.gz

python run_VIBESegmentator.py --img example/mri4.nii.gz --out_path  example/seg4.nii.gz
```
The segmentation is stored in "example/segX.nii.gz." You can view the results with [ITKSnap](http://www.itksnap.org/pmwiki/pmwiki.php) by first drag-and-drop the mriX.nii.gz and then drag-and-drop the segX.nii.gz (with X is a number from before) and click on "Open as Segmentation"

To run this script on your data, update the paths.
