+# Dagster Ops Project
+
+This project demonstrates the same radiomics workflow using **Dagster Ops**.
+Ops are imperative functions that define computation steps. They are connected in a job graph to form the pipeline.
+
+## Features
+- Op-based orchestration for radiomics extraction.
+- Explicit control of execution order via job definitions.
+- Each op corresponds to one stage: image reading, registration, fusion, filtering, mask registration, feature extraction, and writing results.
+
+## Requirements
+- Python 3.10+
+- Dagster
+- SimpleITK
+- Pandas
+- PySERA
+
+Install dependencies:
+```bash
+pip install dagster simpleitk pandas pysera
+
+# Running:
+dagster job execute -f dagster_op_runner.py
+Or:
+run.bat
