int upetExists	(	const char *	upetname,
		char *	hdrfile,
		char *	imgfile
	)

Check if specified image filename is a Concorde/microPET file

Returns:: Returns 0 if it is not, 1 if it is, and both image and header is found.

Parameters:

upetname	Filename, either header file, image file, or base name without extensions. If file is found, then
hdrfile	If upetname is a Concorde/microPET file, then header filename will be written in this char pointer (space needs to allocated by caller); NULL if not needed.
imgfile	If upetname is a Concorde/microPET file, then image filename will be written in this char pointer (space needs to allocated by caller); NULL if not needed.

int upetGetImageDimensions	(	FILE *	fp,
		int *	z,
		int *	x,
		int *	y,
		int *	f
	)

Read image dimensions from header

Parameters:

fp	File pointer to MicroPET image header
z	Pointers to dimensions: planes
x	Pointers to dimensions: columns
y	Pointers to dimensions: rows
f	Pointers to dimensions: frames; if not existent (CT), enter NULL

int upetHeaderReadParameter	(	FILE *	fp,
		char *	parameter,
		char *	value
	)

Read specified parameter value from Concorde/MicroPET header.

Returns:: Returns 0 if parameter was found, even if value is empty, and 1, if parameter was not found, and <0 in case of other errors

Parameters:

fp	File pointer to Concorde/MicroPET header; parameter is read starting from file pointer forward, therefore rewind file pointer before calling this routine if you want to search parameter from beginning
parameter	Pointer to string which contains the header parameter name
value	Pointer to allocated string where parameter value will be written; memory for at least MAX_MICROPET_LINE_LEN chars must be allocated; NULL if not needed.

int upetIsHeader ( char * hdrfile )

Verify that given file is a valid Concorde/microPET file header file.

Returns:: Returns 0 if not, and 1 if it is a valid header file.

Parameters:

hdrfile Concorde/microPET file header filename, with correct extension

int upetReadImagedata	(	FILE *	fp,
		IFT *	ift,
		int	frame,
		float *	data
	)

Reads microPET image data, scaling values to floats if necessary. Reads only one frame at a time!

Returns:: 0 when successful, otherwise <>0.

Parameters:

fp	file opened previously in binary mode
ift	microPET header in IFT struct
frame	frame number to read [1..number of frames]
data	pointer to image float data allocated previously

int upetScanStart	(	FILE *	fp,
		time_t *	scant
	)

Read scan start time from Concorde/MicroPET header.

Returns:: Returns 0 when successful.

Parameters:

fp	File pointer to Concorde/MicroPET header
scant	Pointer to time_t where time and date will be saved
