I am very new in this area and want to download Allen Mouse Connectivity Atlas and perform EDA (Exploratory Data Analysis) on it. Then visualize principal components of the 3D image dataset. All in python. Any guidance? I used this link" Mouse Connectivity — Allen SDK dev documentation", and after setting up the python code could download 11_wks_coronal_644250774_25um_projection_density.nrrd and when run the following code only get header data and metadata but not sure what is 3D image dataset to visualise its PCA. How can I get all the data?
I was wondering to know if you also have any slack channel to communicate easily?
import numpy as np
data_array, metadata = nrrd.read(file_name)
