# ## Mouse Connectivity
#
# This notebook demonstrates how to access and manipulate data in the Allen Mouse Brain Connectivity Atlas. The `MouseConnectivityCache` AllenSDK class provides methods for downloading metadata about experiments, including their viral injection site and the mouse's transgenic line. You can request information either as a Pandas DataFrame or a simple list of dictionaries.
#
# An important feature of the `MouseConnectivityCache` is how it stores and retrieves data for you. By default, it will create (or read) a manifest file that keeps track of where various connectivity atlas data are stored. If you request something that has not already been downloaded, it will download it and store it in a well known location.
#
# Download this notebook in .ipynb format <a href='mouse_connectivity.ipynb'>here</a>.
# In[1]:
from allensdk.core.mouse_connectivity_cache import MouseConnectivityCache
# The manifest file is a simple JSON file that keeps track of all of
# the data that has already been downloaded onto the hard drives.
# If you supply a relative path, it is assumed to be relative to your
# current working directory.
mcc = MouseConnectivityCache(manifest_file='connectivity/mouse_connectivity_manifest.json')

all_experiments = mcc.get_experiments(dataframe=True)

# `MouseConnectivityCache` has a method for retrieving the adult mouse structure tree as an `StructureTree` class instance. This is a wrapper around a list of dictionaries, where each dictionary describes a structure. It is principally useful for looking up structures by their properties.
# In[2]:
# pandas for nice tables
import pandas as pd
# grab the StructureTree instance
structure_tree = mcc.get_structure_tree()
# get info on some structures
structures = structure_tree.get_structures_by_name(['Primary visual area', 'Hypothalamus'])
pd.DataFrame(structures)
# As a convenience, structures are grouped in to named collections called "structure sets". These sets can be used to quickly gather a useful subset of structures from the tree. The criteria used to define structure sets are eclectic; a structure set might list:
#
# * structures that were used in a particular project.
# * structures that coarsely partition the brain.
# * structures that bear functional similarity.
#
# or something else entirely. To view all of the available structure sets along with their descriptions, follow this [link](http://api.brain-map.org/api/v2/data/StructureSet/query.json). To see only structure sets relevant to the adult mouse brain, use the StructureTree:
# In[3]:
from allensdk.api.queries.ontologies_api import OntologiesApi
oapi = OntologiesApi()
# get the ids of all the structure sets in the tree
structure_set_ids = structure_tree.get_structure_sets()
# query the API for information on those structure sets
pd.DataFrame(oapi.get_structure_sets(structure_set_ids))
# On the connectivity atlas web site, you'll see that we show most of our data at a fairly coarse structure level. We did this by creating a structure set of ~300 structures, which we call the "summary structures". We can use the structure tree to get all of the structures in this set:
# In[4]:
# From the above table, "Mouse Connectivity - Summary" has id 167587189
