Analyze PET scan and blood data with this tool. injdifft can calculate time difference between zero times of PET scan and blood data. Zero times are given in two text files in format scan_start_time := YYYY-MM-DD hh:mm:ss, or injection_time := YYYY-MM-DD hh:mm:ss.
The result, time difference (time2-time1 in seconds) will be written in stdout or specified file in format time_difference := . Here is an example on using this program: injdifft -small s95432dy1.v.ift s95432blo.kbq s95432.dift.

Usage: injdifft [options] <timefile1> <timefile2> [output file]

Options:
-min | -sec
Time difference is written in minutes or in seconds (default)
-small
Software ignores time differences of multiples of one hour, that may have been caused by wrong time zone or daylight saving setting in either of the zero times
-h or --help
Print this message and exit
--version or --build
Print software build information and exit
--silent
Program works silently, printing only error and warning messages
