Function Documentation

imgAnalyzeToEcat()

int imgAnalyzeToEcat	(	char *	dbname,
		char *	ecatfile,
		int	flipping,
		int	scanner_type,
		float	zoom,
		int	verbose )

Read Analyze database and write ECAT image frame-by-frame

Returns

Returns errstatus, which is STATUS_OK (0) when call was successful, and >0 in case of an error.

Parameters

dbname	Analyze database name
ecatfile	ECAT image filename, output extension determines the format
flipping	Flipping in Z dimension (usually 1=yes)
scanner_type	Scanner type, 0 if not set
zoom	recon_zoom, 0.0 or 1.0, if not known
verbose	Verbose level; if <=0 then nothing is printed in stdout
