spmdecode

Spmdecode is not a widely standardized standalone tool, and its exact meaning can vary by project. The term most often appears as a function-like identifier within MATLAB-based neuroimaging software such as Statistical Parametric Mapping (SPM), where many utilities use the spm_ prefix. In those contexts, spmdecode would typically be expected to decode or extract information from another data object, such as a results structure produced by an analysis or encoded metadata attached to imaging data. The specific input and output formats, as well as error handling, would be defined by the individual toolbox or script that provides the function.

Because spmdecode is not a single, official component across all releases, its presence and behavior depend on the particular package, version, or custom toolbox in use. Users encountering spmdecode should consult the source code or the project’s documentation to understand its purpose, required inputs, and produced outputs. If a user meant a different function (for example, a similarly named spm_decode) or a non-SPM component, they should refer to the relevant repository or documentation for that project.

In practice, if you encounter spmdecode in a MATLAB workflow, you would typically call it within MATLAB, passing the relevant data object or file that needs decoding, and handling whatever decoded structure or values it returns. As with any specialized function, clear knowledge of the surrounding code and data formats is essential.
