+# TF2.4_IVIM-MRI_CodeCollection
+
+This project is designed to run the `nifti_wrapper` script using a Docker container. Below are the steps to build and run the Docker image.
+
+## Prerequisites
+
+- Docker must be installed on your system. 
+
+## Directory Structure
+
+```
+~/TF2.4_IVIM-MRI_CodeCollection/
+│
+├── Docker/
+│   └── Dockerfile
+│
+├── WrapImage/
+│   └── nifti_wrapper.py
+│
+└── requirements.txt
+```
+
+## Options
+
+Before running the Docker container, here are the available options for the `Docker image` script:
+
+- `input_file`: Path to the input 4D NIfTI file.
+- `bvec_file`: Path to the b-vector file.
+- `bval_file`: Path to the b-value file.
+- `--affine`: Affine matrix for NIfTI image (optional).
+- `--algorithm`: Select the algorithm to use (default is "OJ_GU_seg").
+- `algorithm_args`: Additional arguments for the algorithm (optional).
+
+## Building the Docker Image
+
+1. Open a terminal and navigate to the project directory:
+
+    ```sh
+    cd ~/TF2.4_IVIM-MRI_CodeCollection
+    ```
+
+2. Build the Docker image using the `docker build` command:
+
+    ```sh
+    sudo docker build -t tf2.4_ivim-mri_codecollection -f Docker/Dockerfile .
+    ```
+
+## Running the Docker Container
+
+1. Once the image is built, you can run the Docker container using the `docker run` command. This command runs the Docker image with the specified input files:
+
+    ```sh
+    sudo docker run -it --rm --name TF2.4_IVIM-MRI_CodeCollection \
+        -v ~/TF2.4_IVIM-MRI_CodeCollection:/usr/src/app \
+        -v ~/TF2.4_IVIM-MRI_CodeCollection:/usr/app/output \
+        tf2.4_ivim-mri_codecollection brain.nii.gz brain.bvec brain.bval
+    ```
+
+    Replace `brain.nii.gz`, `brain.bvec`, and `brain.bval` with the actual file names you want to use.
