#define NIFTI_NEEDS_SWAP (  h    )     ( (h).dim[0] < 0 || (h).dim[0] > 7 )
 

Check if a nifti_1_header struct needs to be byte swapped. Returns 1 if it needs to be swapped, 0 if it does not.

#define NIFTI_ONEFILE (  h    )     ( (h).magic[1] == '+' )
 

Check if a nifti_1_header struct says if the data is stored in the same file or in a separate file. Returns 1 if the data is in the same file as the header, 0 if it is not.
