The MGH/MGZ Volume Format
WORK IN PROGRESS
The .mgh file format is used to store high-resolution structural data and other data which are to be overlaid on the high-resolution structural volume. A .mgz file is a .mgh file that has been compressed with ZLib.
The MGH format is proprietary, defined by the NMR Center (at Massachusetts General Hospital). Short of having a formal specification of this format, the next best thing is a snapshot of the C code showing how the file is read and written:
attachment:mri.h - a .mgh file merely stores the MRI data structure, defined in mri.h
- attachment:matrix.h - MRI data structure contains MATRIX
- attachment:mriio.c - see 'MRIreadHeader', 'mri_read', and 'mri_write' routines
- attachment:mri.c - contains helper routines used in mriio.c
- attachment:mri_info.c - see 'do_file' routine
- attachment:mri_convert.c - big example of reading and writing .mgh and .mgz file
