Human Reference Genomes
This dataset includes two human-genome references assembled by the Genome Reference Consortium: Hg19 and Hg38.
For more information on Hg19 (GRCh37) data, see the GRCh37 report at NCBI.
For more information on Hg38 data, see the GRCh38 report at NCBI.
Other details about the data can be found at NCBI RefSeq site.

Data source
This dataset is sourced from two FTP locations:
Blob names are prefixed beginning with the “vertebrate_mammalian” segment of the URI.
Data volumes and update frequency
This dataset contains approximately 10 GB of data and is updated daily.
Storage location
This dataset is stored in the West US 2, West Central US and South Central US Azure regions. Allocating compute resources in West US 2 or West Central US or South Central US is recommended for affinity.

Getting the Reference Genomes from Azure Open Datasets
Several public genomics data has been uploaded as an Azure Open Dataset here. We create a blob service linked to this open dataset. You can find examples of data calling procedure from Azure Open Datasets for Reference Genomes dataset in below:
Users can call and download the following path with this notebook: 'https://datasetreferencegenomes.blob.core.windows.net/dataset/vertebrate_mammalian/Homo_sapiens/latest_assembly_versions/GCF_000001405.39_GRCh38.p13/GCF_000001405.39_GRCh38.p13_assembly_structure/genomic_regions_definitions.txt'
Important note: Users need to log in their Azure Account via Azure CLI for viewing the data with Azure ML SDK. On the other hand, they do not need do any actions for downloading the data.
Calling the data from 'Reference Genome Datasets'
import azureml.core
print("Azure ML SDK Version: ", azureml.core.VERSION)
from azureml.core import Dataset
reference_dataset = Dataset.File.from_files('https://datasetreferencegenomes.blob.core.windows.net/dataset')
mount = reference_dataset.mount()
import os
REF_DIR = '/vertebrate_mammalian/Homo_sapiens/latest_assembly_versions/GCF_000001405.39_GRCh38.p13/GCF_000001405.39_GRCh38.p13_assembly_structure'
path = mount.mount_point + REF_DIR
with mount:
print(os.listdir(path))
import pandas as pd
# create mount context
mount.start()
# specify path to genomic_regions_definitions.txt file
REF_DIR = 'vertebrate_mammalian/Homo_sapiens/latest_assembly_versions/GCF_000001405.39_GRCh38.p13/GCF_000001405.39_GRCh38.p13_assembly_structure'
metadata_filename = '{}/{}/{}'.format(mount.mount_point, REF_DIR, 'genomic_regions_definitions.txt')
# read genomic_regions_definitions.txt file
metadata = pd.read_table(metadata_filename)
