N-dimensional, homogeneous arrays¶
By using a simple convention to describe metadata about the array axes, basic information is available to make sensible interpretation of the array’s content.
Useful for neuroscience data types¶
- Electron microscopy: 3D array, 3 spatial dimension after alignment
- Optical microscopy: 4D array, 3 spatial dimension and 1 channel dimension
- Labeling
- Functional MRI/PET: 4D array, with 3 spatial and 1 temporal dimension
- Structural MRI: 3D array, with 3 spatial dimensions
- Diffusion MRI: 4D array, with 3 spatial dimension and 1 dimension for gradient directions Contain metadata tables for b-values and b-vectors
Tool supporting this specification¶
None so far. A zebra fish dataset available as HDF5 files uses a similar specification for axes units.
