Listing the Samples registered into DeepBlue
# Samples | |
# DeepBlue organizes the Biological Names into BioSources and Samples. | |
# While the BioSources are the biological entities, the Samples are the instances of these entities. | |
# For example, the BioSource blood. It refer to any blood, but a blood from a specific donor, time, or caractistic will have be a specific sample. | |
# All Samples refer to a BioSource and a set o attributes, that we name metadata. | |
import xmlrpclib | |
# Before going further, we must set up the client: | |
url = "http://deepblue.mpi-inf.mpg.de/xmlrpc" | |
server = xmlrpclib.Server(url, encoding='UTF-8', allow_none=True) | |
# You can use the anonymous key or your own user key | |
user_key = "anonymous_key" | |
# The command list_samples is used to list all Samples from a given BioSource: | |
server.list_samples("blood", {}, user_key) | |
# Output: | |
# ['okay', | |
# [['s3', | |
# {'_id': 's3', | |

# The samples are automatically load from the Epigenetics Projects (BLUEPRINT, ENCODE, Roadmap) | |
# and we are always trying to perform the best match between the mapped BioSource and the Biological Entitiy of the Experiment. | |
# It is important to remid that the metadata key names are not uniformized, so depending the Project or Sample, | |
# there can have different names with the same semantic. It is possible to list only the Knowing the Samples Metadata fields, |
