arlkup can calculate blood flow value, help you calculate blood flow value look-up table from [O-15]H2O blood curve for using with PET in vivo autoradiographic (ARG) method (1-5).
The command-line arguments must be given in this order:
1. Blood datafile (calibrated and corrected for decay)
2. Partition coefficient p [mL/mL]
3. Maximal blood flow [mL/(min*100mL)]
4. Integration start time [sec]
5. Integration duration [sec]
6. Size of the table (nr of rows)
7. Filename for the look-up table

Options:
-static=<y|N>
The look-up table integral can be corrected for physical decay as single frame when static PET scan was performed (y), or dynamically (N, the default).
-h or --help

--silent
Program works silently, printing only warnings and error messages
--verbose
