| NonNegativity | All except [spherical coordinates](#encoding-spherical) and [3-vectors](#encoding-3vector) | OPTIONAL. String. Options are: { `regularized`, `constrained` }. Specifies whether, during model fitting, the parameter was regularised to not take extreme negative values, or was explicitly forbidden from taking negative values. |
| OrientationEncoding | Any | REQUIRED if dimensionality of NIfTI image is greater than three. Dictionary. Provides information requisite to the interpretation of orientation information encoded in each voxel; more details below. |
| ParameterURL | Any | OPTIONAL. String. URL to documentation that describes the specific model parameter that is encoded within the data file. |
| ResponseFunction | [Spherical harmonics](#encoding-sh) | OPTIONAL. Dictionary. Specifies a response function that was utilised by a deconvolution algorithm; more details below. |
