ecat2ana - tpcclib 0.7.7 © 2021 by Turku PET Centre

Converts ECAT 6.3 images or ECAT 7 image volumes to Analyze 7.5 image format.
Conversion can also be done using ImageConverter (.NET application).
 
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, which can be created optionally.
SIF can also be created using other software.
 
By default, data is saved in big endian byte order (Sun Sparc).
 
Usage: ecat2ana [Options] ecatfile(s)
 
Options:
 -Little or -pc or -intel
     Data is saved in little endian (PC Intel) byte order.
 -Big 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.
 -sif
     SIF is saved with Analyze files; note that existing SIF will be
     overwritten.
 -frames
     Time frames are saved as separate Analyze files.
 -h, --help
     Display usage information on standard output and exit.
 -v, --version
     Display version and compile information on standard output and exit.
 -d[n], --debug[=n], --verbose[=n]
     Set the level (n) of debugging messages and listings.
 -q, --quiet
     Suppress displaying normal results on standard output.
 -s, --silent
     Suppress displaying anything except errors.
 
Example:
  ecat2ana -o=anal *.v
 
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.'
