Download the 100um energy volume for the Mouse Connectivity Projection experiment 183282970:

http://api.brain-map.org/grid_data/download_file/183282970?image=energy

Download the 25um injection volume for the Mouse Connectivity Projection experiment 183282970:

http://api.brain-map.org/grid_data/download_file/183282970?image=injection&resolution=25

Download the energy volume for the Mouse Brain Atlas' coronal Adora2a experiment.

    First, search for relevant experiments' IDs (SectionDataSets):

http://api.brain-map.org/api/v2/data/query.xml?criteria=
model::SectionDataSet,
rma::criteria,[failed$eq'false'],products[abbreviation$eq'Mouse'],plane_of_section[name$eq'coronal'],genes[acronym$eq'Adora2a']

    Then, download the energy volume for each of the experiments' IDs:

http://api.brain-map.org/grid_data/download/72109410?image=energy

Parameters

filename

Integer

ID of the desired SectionDataSet.

image

String

Explicitly choose the desired image volume. Valid volumes are energy and density. An additional volume of injection is available for projection SectionDataSets. 

resolution

Integer

For projection data, available resolutions are 10, 25, 50, and 150 (in microns). For adult mouse gene expression SectionDataSets, only 200um resolution data is available and will be returned regardless of the input value.

Response

For Mouse Projection data, the response will be a single 32-big floating point Nrrd image named for the type of requested image (e.g. energy_(resolution).nrrd).

For Mouse Brain Atlas data, the response will be a .zip file containing Meta Image header (.mhd) and (.raw) pair.
