disp4dft - tpcclib 0.7.3 © 2019 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
