dftinteg - tpcclib 0.7.3 © 2019 by Turku PET Centre

Calculation of an AUC (integral over time) from regional or plasma TACs.
 
Usage: dftinteg [Options] tacfile starttime integrationtime aucfile
 
Enter the start time and integration time in the same units that are used
in the TAC file. Note that 3rd argument is not the integration end time.
Program will automatically set the integration start time and duration
based on the time range in the TAC file, if both are set to zero.
AUC/mean is by default written in DFT format, or in RES format if filename
has extension .res.
 
Options:
 -avg
     Average during specified range is calculated instead of AUC.
 -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: calculate AUC(32-302) with command
  dftinteg s5998dy1.dft 32 270 s5998int.dft
Example 2: integrate the regional TACs from a static or dynamic study
from the start time of the first frame to the end of the last frame:
  dftinteg a773dy1.dft 0 0 a773int.dft
Example 3: mean between 0 and 10 is calculated and saved in result format:
  dftinteg -avg ec4568.dft 0 10 ec4568_mean0-10.res
