Calculates robust estimates for ECAT 6.3 parametric image ROI average ROI information is based on ECAT 6.3 template image where different ROIs have different labels. Usage: re4img [-<m|l|t|h|a>] <ECAT6 parametric image> <ECAT6 template>, <configuration file> <result file(*.res)> ROI names and representative labels (integers) in template image are given in an ASCII file *.conf: background 0 cerebellum 1 whitematter 2 graymatter 3 Warning: Region names can't contain spaces eq. use whitematter instead of white matter Maximum number of ROIs is 100. With option -m only median is calculated. With option -l only least median of squares estimate is calculated With option -t only least trimmed square estimate is calculated. With option -h only Huber's M-estimate is calculated. With option -d distributions inside each ROI are printed into files named according to ROI names. Least median of squares and least trimmed square methods don't work for uniformly distributed data. This has to be considered when using test data - real data is never uniformly distributed. With option -a average TAC:s of dynamic image are calculated. --version Print program and library build information and exit. See also: img2dft
