This tutorial shows how to download the MAREoS dataset from the web¶
Let's start with the imports¶
# We can call the helper funtion to load all the dataset (aprox 3MB).
# The files will be stored in the cache, so we don't have to worry about them
datasets = load_MAREoS()
dict_keys(['eos_simple1', 'eos_simple2', 'eos_interaction1', 'eos_interaction2', 'true_simple1', 'true_simple2', 'true_interaction1', 'true_interaction2'])
We have now all the datasets in a dictionary. There is a total of 8 datasets.¶
# Select one dataset and explore what is inside the dictionary
dataset = datasets["eos_simple1"]
print(dataset.keys())
dict_keys(['X', 'y', 'sites', 'covs', 'folds'])
# Let's unpack what is inside the keys. This is the typical way you can use
# the dataset for further downstream analysis.
X = dataset["X"]
y = dataset["y"]
print(f"Load X with shape:{X.shape} and y:{y.shape}")
Load X with shape:(1001, 14) and y:(1001,)
Load datasets by condition¶
# You can use the helper function to only return a part of the datasets
datasets = load_MAREoS(effects="eos")
print(datasets.keys())
dict_keys(['eos_simple1', 'eos_simple2', 'eos_interaction1', 'eos_interaction2'])
dict_keys(['eos_simple1', 'eos_simple2'])
datasets = load_MAREoS(effects="eos", effect_types="simple", effect_examples="1")
print(datasets.keys())
dict_keys(['eos_simple1'])
Returning the dataset as DataFrame allows to see the simulated areas¶
You can chose to load the dataset as pandas.DataFrame, with has the simulated areas of the brain.
datasets = load_MAREoS(effects="eos", effect_types="simple", effect_examples="1", as_numpy=False)
dataset = datasets["eos_simple1"]["X"]
dataset.head()
