tacmean - tpcclib 0.7.7 © 2021 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]
TACs are weighted by the VOI sizes, if available in the TTAC file.
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 curve is calculated and saved; weights are not applied.
CV curve is calculated and saved; weights are not applied.
