Function Documentation

int anaDatabaseExists	(	const char *	dbname,
		char *	hdrfile,
		char *	imgfile,
		char *	siffile
	)

Check if Analyze database files exist (*.hdr, *.img, and optionally *.sif).

Parameters

dbname	analyze database name that is tested. String may contain standard extensions .hdr, .img or .sif.
hdrfile	pointer to an allocated string, where existing header filename is written. If not found, then set to "". NULL can be entered, if not needed.
imgfile	pointer to an allocated string, where existing image filename is written. If not found, then set to "". NULL can be entered, if not needed.
siffile	pointer to an allocated string, where existing sif filename is written. If not found, then set to "". NULL can be entered, if not needed.

Returns: 0, if files do not exist, 1 if .img and .hdr do exist, and 2, if also .sif exists.

int anaExists ( const char * dbname )

Check if Analyze files exist.

Parameters

dbname basename of Analyze7.5 file.

Returns: 0, if they do not, 1 if .img and .hdr do exist, and 2, if also .sif exists.

int anaFlipping ( )

Check whether Analyze image is flipped in z-direction when it is read from/written to file (x,y-flipping is done always)

Returns: 1 if Analyze data is flipped

int anaMakeSIFName	(	const char *	dbname,
		char *	siffile
	)

Make SIF filename from Analyze 7.5 database name.

Parameters

dbname	analyze 7.5 database name (including possible path but not extension
siffile	pointer to allocated space for SIF filename

Returns: Returns 0 if SIF file is accessible, 1 if invalid input, 2 if sif name not found.

Read analyze header contents.

Parameters

filename	name of file to read (including path and extension)
h	Pointer to previously allocated header structure

Returns: 0, if ok, 1 if invalid input, 2 if file cannot be opened, 3 if header cound not be read, 4 if header image dimension could not be read

int anaReadImagedata	(	FILE *	fp,
		ANALYZE_DSR *	h,
		int	frame,
		float *	data
	)

Read Analyze 7.5 image data, convert byte order if necessary, and scale values to floats. Reads only one frame at a time!

Parameters

fp	file opened previously in binary mode
h	analyze header read previously
frame	frame number to read [1..number of frames]
data	pointer to image float data allocated previously

int anaRemove ( const char * dbname )

Remove header and data files belonging to specified Analyze 7.5 database. SIF is not deleted in any case.

Returns: 0 when call was successful, 1 if header file deletion failed, 2 if data file deletion failed. Call is considered successful, if database does not exist initially.
