struct nifti_1_header
Data structure defining the fields in the nifti1 header. This binary header should be found at the beginning of a valid NIFTI-1 header file. struct nifti1_extender
This structure represents a 4-byte string that should follow the binary nifti_1_header data in a NIFTI-1 header file. If the char values are {1,0,0,0}, the file is expected to contain extensions, values of {0,0,0,0} imply the file does not contain extensions. Other sequences of values are not currently defined. struct nifti1_extension
Data structure defining the fields of a header extension.

Typedefs

typedef struct nifti_1_header nifti_1_header
typedef struct nifti1_extender nifti1_extender
typedef struct nifti1_extension nifti1_extension

#define FPS_INTO_DIM_INFO(fd, pd, sd) Value:

( ( ( ((char)(fd)) & 0x03)      ) |                                        ( ( ((char)(pd)) & 0x03) << 2 ) |                                        ( ( ((char)(sd)) & 0x03) << 4 )  )

#define NIFTI_5TH_DIM(h) ( ((h).dim[0]>4 && (h).dim[5]>1) ? (h).dim[5] : 0 ) Check if a nifti_1_header struct contains a 5th (vector) dimension. Returns size of 5th dimension if > 1, returns 0 otherwise.

#define NIFTI_INTENT_NONE 0 default: no intention is indicated in the header.

#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.

#define NIFTI_VERSION(h) Value:

( ( (h).magic[0]=='n' && (h).magic[3]==' '    &&          ( (h).magic[1]=='i' || (h).magic[1]=='+' ) &&          ( (h).magic[2]>='1' && (h).magic[2]<='9' )   )     ? (h).magic[2]-'0' : 0 )

Given a nifti_1_header struct, check if it has a good magic number. Returns NIFTI version number (1..9) if magic is good, 0 if it is not.

#define SPACE_TIME_TO_XYZT(ss, tt) Value:

(  (((char)(ss)) & 0x07)                                      | (((char)(tt)) & 0x38) )
