ecat2ana 1.0.2 © 2003-2010 by Turku PET Centre
Convert ECAT 6.3 images or ECAT 7 image volumes to Analyze 7.5 image format.
The resulting Analyze database consists of two files, Analyze image (*.img)
and header file (*.hdr).
Analyze image format does not contain information on the frame times.
Frame times can be retrieved from SIF file. If SIF file does not exist,
it can be created using program cti2sif and kept with the Analyze files.
By default, data is saved in big endian byte order (Sun Sparc).
Usage: ecat2ana [Options] <ECAT file(s)>
Options:
-L[ittle] or -pc or -i
Data is saved in little endian (PC Intel) byte order.
-B[ig] or -sun or -sparc
Data is saved in big endian (Sun Sparc, Motorola, PowerPC) byte order
(default).
-O=<output path>
Data directory for Analyze files; by default the output directory
ana_unix_files or ana_pc_files is created under input directory.
-flip=<y|n>
Override the default and environment variable ANALYZE_FLIP setting
by always flipping/not flipping image in z-direction (planes).
If environment variable is not set, then default is y.
Images are always flipped in x,y-directions.
-frames
Frames are saved as separate Analyze files.
-h or --help
Print this message and exit.
-v, --version or --build
Print software build information and exit.
--verbose
Program prints more information about what it is doing.
--silent
Program works silently, printing only error and warning messages.
Example:
ecat2ana *.img
Specific extensions to Analyze 7.5 format:
-Scale factor to retain quantitation in image_dimension.funused1
-Isotope halflife (sec) in image_dimension.funused3;
this does not imply whether data is corrected for decay or not.
-String in data_history.descrip tells whether data is corrected for decay;
'Decay corrected.' or 'No decay correction.'
