+Each subset can be loaded into python using the Huggingface [datasets](https://huggingface.co/docs/datasets/index) library.
+First, from the command line install the `datasets` library
+
+    $ pip install datasets
+
+then, from within python load the datasets library
+
+    >>> import datasets
+
+### Load Dataset
+
+Load PISCES-CulledPDB dataset.
+
+    >>> pisces_culledpdb = datasets.load_dataset('RosettaCommons/PISCES-CulledPDB')
+    Downloading readme: 4.02kB [00:00, 1.08MB/s]
+    Downloading data: 100%|█████████████████████████████████████████████████████████████████████████████████████████████████| 69.3M/69.3M [00:13<00:00, 5.10MB/s]
+    Generating train split: 100%|██████████████████████████████████████████████████████████████████████████| 3632659/3632659 [00:02<00:00, 1637871.99 examples/s]
+
+and the dataset is loaded as a `datasets.arrow_dataset.Dataset`
+
+    >>> pisces_culledpdb
+    DatasetDict({
+        train: Dataset({
+            features: ['pdb_chain', 'cluster_id', 'split'],
+            num_rows: 3632659
+        })
+    })
+
+which is a column oriented format that can be accessed directly, converted in to a `pandas.DataFrame`, or `parquet` format, e.g.
+    
+    >>> pisces_culledpdb.data.column('pdb_chain')
+    >>> pisces_culledpdb.to_pandas()
+    >>> pisces_culledpdb.to_parquet("dataset.parquet")
