Parameters
filename |
Integer |
ID of the desired SectionDataSet. |
volumes |
Array (optional) |
Explicitly list the desired volumes as a comma-separated list. Valid volumes are energy, intensity, and density. |
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. |
