Converting MAT Files to HDR Format Files for SPM Integration

To convert a .mat file to HDR format file using SPM, follow this structured approach with technical implementation details: 1. Launch SPM and navigate to the "File" menu in the menu bar. This initializes the SPM environment and loads necessary libraries for file conversion operations. 2. Select the "Import" functionality and specify the target .mat file for conversion. The import module handles matrix data extraction and validates file structure compatibility. 3. In the import configuration dialog, set "HDR" as the output format specification. This triggers SPM's internal conversion algorithm that maps matrix data to HDR's header and image data structure. 4. Configure output parameters including spatial resolution and dimensional specifications. The conversion process utilizes interpolation methods when resizing image data, maintaining data integrity through bilinear or nearest-neighbor algorithms. 5. Execute the conversion by clicking "OK", initiating SPM's built-in write function that generates the HDR file with appropriate header information and data formatting. Upon completion, the resulting HDR file preserves the original matrix data in a standardized neuroimaging format, suitable for volume rendering, voxel-based analysis, and integration with other SPM processing pipelines. The conversion maintains spatial relationships and data precision through SPM's validated image transformation routines.
