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. |
