disp4dft - tpcclib 0.8.0 © 2023 by Turku PET Centre
Add dispersion effect to ideal TAC data (ON), or correct a measured data set
for dispersion (OFF) (1, 2).
The time constant of the dispersion must be given in the same time units as
those that are used in the data file.
Program output is written in file in the same format as the input datafile.
Usage: disp4dft [Options] ON|OFF tacfile dispersion outputfile
Options:
-Log
Dispersion time and other log information is written as comments in
the corrected TAC file.
-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 1: check that specified data files are suitable as input TACs
