 This dataset contains several microstructure treatments:
 1. [`variable_radius.zip`](https://huggingface.co/datasets/cmudrc/porous-microstructure-strain-fields/blob/main/variable_radius.zip) - Ten microstructures with defects of variable radii, from 0.01 mm to 0.5 mm. To load it, run: ```datasets.load_dataset(data_files=['variable_radius.zip'])```
 2. [`variable_number.zip`](https://huggingface.co/datasets/cmudrc/porous-microstructure-strain-fields/blob/main/variable_number.zip) - Ten microstructures with different numbers of defects, from 20 to 200. To load it, run:  ```datasets.load_dataset(data_files=['variable_number.zip'])```
-3. [`circular_defects.zip`](https://huggingface.co/datasets/cmudrc/porous-microstructure-strain-fields/blob/main/circular_defects.zip) - This data contains image data of 1000 samples of microstructures with 100 circular porosity defects having their radii uniformly distributed in the range 0.1 – 0.5 mm, and their corresponding strain fields.  To load it, run:  ```datasets.load_dataset(data_files=['circular_defects.zip'])```
