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. An .mgz file is a .mgh file that has been compressed with ZLib. It is proprietary format, 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 declaring the MGH format, and examples of how a file is read and written:
- attachment:mri.h - the MRI data structure defines the MGH
- attachment:matrix.h - MRI data structure contains MATRIX
- attachment:mriio.c - see MRIreadHeader, mri_read, and mri_write routines
- attachment:mri.c - contains mriio.c helper routines
- attachment:mri_info.c - see do_file routine
- attachment:mri_convert
