+Data Access
+===========
+
+The electrophysiology data files for the PatchSeq experiments released by the
+Allen Institute are stored in `Neurodata Without Borders 2.0 <https://nwb.org>`_ (NWB) format.
+The files are hosted on the `Distributed Archives for Neurophysiology Data Integration (DANDI) <https://dandiarchive.org>`_.
+
+The PatchSeq data release is composed of  two archives:
+
+Mouse data archive (114 GB): `<https://dandiarchive.org/dandiset/000020>`_
+
+Human data archive (12 GB): `<https://dandiarchive.org/dandiset/000023>`_
+
+Each archive is accompanied by the corresponding file manifest and the experiment metadata tables.
+
+The file manifest table contains information about the files included in the archive,
+their location ("archive_uri" column) and the corresponding cell("cell_specimen_id" column).
+The file manifest combines information about several different data modalities (see the "technique" column)
+recorded from each cell. The files with the intracellular electrophysiological recordings stored on DANDI are denoted as
+"technique" = intracellular_electrophysiology.
+
+In turn, the experiment metadata table includes information about the experimental conditions
+for each cell("specimen_id" column). This table could be used to select the desired cells
+satisfying particular experimental conditions. Then, given the desired "specimen_ids",
+you can find the corresponding DANDI urls of these data from the file manifest.
+
+IPFX includes a utility that provides file manifest and experiment data of the published archives.
+
+For example, to obtain detailed information about Human data archive:
+
+.. code-block:: python
+
+    from ipfx.data_access import get_archive_info
+    archive_url, file_manifest, experiment_metadata = get_archive_info(dataset="human")
+
+where ``archive_uri`` is the DANDI URL for the Human data,
+``file_manifest`` is a pandas.DataFrame of file manifest and
+``experiment_metadata`` is a pandas.DataFrame of experiment metadata.
+To obtain the same information for the Mouse data, change to `dataset="mouse"` in the function argument.
+
+You can download data files by directly entering the DANDI's archive_uri in your browser.
+Alternatively, a more powerful option is to install DANDI's command line client:
+
+.. code-block:: bash
+
+    pip install dandi
+
+With client installed, you can easily download individual files or an entire archive as:
+
+.. code-block:: bash
+
+    dandi download --output-dir <DIRECTORY> <URL>
+
+where <DIRECTORY> is the existing directory on your file system
+and <URL> is the url of a file or an archive.
