1. pyradiomics-extension is allowed users input original DICOM files and RTstruture;
2. computation of radiomics features on specific ROI in RTstruture;
3. semi-automatic ROI name matching
4. allow users to output radiomics features in different formats (e.g., RDF, csv, xml)

1. install pyradiomics
2. Download pyradiomics-extension in the sub-directory of pyardiomics
3. provide input parameters in "UserInputFile.txt" (see below input) and parameters of pyradiomics in "Params.yaml"
4. execute MainScript.py
5. Results are saved in "Output_path"

Input: four parameters of pyradiomics-extension are in "UserInputFile.txt". Note that, Users must provide the parameters in separate lines (i.e., 1,2,3 and 4).

1. Img_path. Local path of DICOM images
2. RT_path. Local path of RTstruct files
3. Output_path. Local path of output
4. ROI name (e.g., [Gg][Tt][Vv][-][1])

Output: the default output of pyradiomics-extension V1.0 is in Resource Description Framework (RDF) format.
