+Example for extracting feature using your own data:
+```python
+from src.benchmark.model_util import extract_opera_feature
+
+# array of filenames
+sound_dir_loc = np.load(feature_dir + "sound_dir_loc.npy")
+opera_features = extract_opera_feature(sound_dir_loc,  pretrain="operaCT", input_sec=8, dim=768)
+np.save(feature_dir + "operaCT_feature.npy", np.array(opera_features))
+```
