tacmean - tpcclib 0.7.8 © 2022 by Turku PET Centre

Calculate average TAC of all regional TACs in the TTAC file.
Weighted average TAC can be used as a 'head curve' in time delay correction,
if reliable count-rate data is not available.
Optionally, the same file name can be given to TTAC file and avg file to
add the mean TAC into the original data file.
 
Usage: tacmean [options] ttacfile [avgfile]
 
Options:
 -ws
     TACs are weighted by the VOI sizes, if available in the TTAC file.
 -wf=<filename>
     TACs are weighted by values given in parameter file.
     If any TAC is not found in parameter file or value is invalid, zero
     weight is applied to that TAC.
     Parameter named as 'weight' or 'w' is used if available; if not then
     the first parameter is used.
 -sd=<filename>
     SD curve is calculated and saved; weights are not applied.
 -cv=<filename>
     CV curve is calculated and saved; weights are not applied.
 -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.
