Exporting a Dataset – Rhino Federated Computing

Exporting a dataset makes it accessible in your /rhino_data directory in your Rhino Client. You can then access the dataset via SFTP or client-mounted storage. Then, you can use the data outside of the Rhino platform. You can only export datasets that belong to your workgroup if you have the Manage This Site's Datasets Permission. For more information, see Viewing Your Project's Permissions Policy.

To export a dataset, do the following.

In the Dataset page, on the overview page, select the three-dot menu for the dataset that you want to export.
Select Export Dataset. The Export Dataset window opens.
Type where you want to export the dataset, then select the Export button.
```
/rhino_data/export_folder
```

Structure of your exported dataset

Your exported dataset will be structured similarly to how datasets are structured for code run inputs and outputs. In particular, your dataset will have a directory structure that resembles:

.
|___ dataset.csv
|___ metadata.json
|___ dicom_data/
|______ ...
|___ file_data/
|______ ...

Inside this directory, you will find some (or all) of the following elements:

dataset.csv - a comma-separated value file with the tabular data from your dataset
metadata.json - a json containing information about the dataset (e.g., which workgroup it belonged to, when it was created)
dicom_data/ - a directory containing any DICOM files associated with your dataset
file_data/ - a directory containing any generic files associated with your dataset (e.g., jpegs)

Metadata Structure

The metadata.json file contains the following key-value pairs:

dataset_uid: str
dataset_name: str
dataset_version: int
data_schema_uid: str
data_schema_name: str
workgroup_uid: str
workgroup_name: str
creation_time: str
num_rows: int
num_fields: int
fields: List[str]

See an example below:

{
  "dataset_uid": "a186342e-7a0d-46cd-819d-b751f361108d",
  "dataset_name": "Clinic Dataset",
  "dataset_version": 0,
  "data_schema_uid": "51ee196b-f978-4ca9-9583-6c0309bc3a4a",
  "data_schema_name": "Diabetes Schema",
  "workgroup_uid": "5a2eee3b-dbf2-492d-93fa-1175ae2ad7a9",
  "workgroup_name": "Clinic",
  "creation_time": "2022-09-28 11:51:57.070000+00:00",
  "num_rows": 275,
  "num_fields": 10,
  "fields": [
    "Pregnancies",
    "Age",
    "Height",
    "Weight",
    "Glucose",
    "BloodPressure",
    "SkinThickness",
    "Insulin",
    "DiabetesPedigreeFunction",
    "Outcome"
  ]
}

Access to your exported dataset

Once exported, the exported dataset can be accessed using the instructions below.

SFTP

Log into the client via SFTP and run the following command.

sftp> get export_folder
