Download the 200um energy and intensity volumes for Mouse Brain Atlas SectionDataSet 69816930:
http://api.brain-map.org/grid_data/download/183282970?include=energy,intensity
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?include=energy
Parameters
ID |
Integer |
ID of the desired SectionDataSet. |
include |
String (optional) |
Explicitly choose the desired image volumes. Valid volumes are energy, density, and intensity. Supply multiple volumes in a comma-delimited list (e.g. "include=energy,density,intensity"). By default, only energy is returned. |
Response
Zip file (.zip) containing a folder filled with the default files (data_set.xml, energy.mhd, energy.raw) or the requested data volumes.
data_set.xml |
XML file with details regarding the specimen and images that is only returned if the volumes parameter is null. |
energy.mhd |
A simple text header file in MetaImage format describing the volume. This file is returned by default if the volumes parameter is null. |
energy.raw |
A raw uncompressed float (32-bit) little-endian volume representing average expression energy per voxel. A value of "-1" represents no data. This file is returned by default if the volumes parameter is null. |
density.mhd |
A simple text header file in MetaImage format describing the volume. |
density.raw |
A raw uncompressed float (32-bit) little-endian volume representing average expression density per voxel. A value of "-1" represents no data. |
intensity.mhd |
A simple text header file in MetaImage format describing the volume. |
intensity.raw |
A raw uncompressed float (32-bit) little-endian volume representing average expression intensity per voxel. A value of "-1" represents no data. |
injection.mhd |
A simple text header file in MetaImage format describing the volume. |
injection.raw |
A raw uncompressed float (32-bit) little-endian volume representing the proportion of pixels within each voxel that were within the manually annotated injection site. |

Parameters
ID |
Integer |
ID of the desired SectionDataSet. |
image |
String (optional) |
Explicitly choose the desired image volume. Valid volumes are density, energy, and injection. |
resolution |
Integer (optional) |
For projection data, available resolutions are 10, 25, 50, and 100 (in microns). |
Response
For Mouse Projection data, the response will be a single 32-big floating point Nrrd image named for the requested image type and resolution.
