Estimate the binding potential (BP) from simplified reference tissue model [1]. The model is solved using the basis function approach [2], similar to the RPM program for producing BP images. Parameters: 1) Tissue TAC file (*.dft; must be corrected for radioactive decay) 2) Name of reference region in tissue file, or name of file containing reference tissue TAC 3) Isotope (C-11, F-18, ...) 4) Result file (existing file is overwritten) 5) Fitted TAC file (optional) Tissue TAC file must contain weights. Options: -min=<value (1/min)> Set minimum value for theta3; it must be >= k2min/(1+BPmax)+lambda. Default is 0.01 min-1. Lambda for F-18 is 0.0063 and for C-11 0.034. -max=<value (1/min)> Set maximum value for theta3; it must be <= k2max+lambda. Default is 0.60 min-1. -nr=<value> Set number of basis functions; default is 1000. -bf=<filename> Basis functions are written in specified DFT file. -E=<Fit end time (min)> Use data from 0 to end time; by default, model is fitted to all frames. -DVR Instead of BP, program saves the DVR (=BP+1) values. -h or --help Print this message and exit -v, --version, or --build Print software build information and exit --silent Program works silently, printing only warnings and error messages.
