PET TACs are simulated with short sample time intervals.
This program sums up those points within specified time frames to simulate
a measured PET tissue uptake curve.
Usage: simframe [options] tacfile framefile newfile [isotope]
 -sec or -min
     Sample times are known to be in seconds or minutes, but is not
     specified or is wrong in TAC file.
     Frame mid time is written in output file instead of start and end times.
 -i  Calculates integrals at frame mid times, instead of frame averages;
     not available with [isotope].
 -ii Calculates 2nd integrals at frame mid times, instead of frame averages;
     not available with [isotope].
     Program allows extensive extrapolation.
 -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.
TAC file can contain more than one TAC.
Time frames data can be in SIF or TAC format. Alternatively, file can consist
of one or two columns of data, containing either 1) frame durations, or
2) frame start times and frame durations; frame time units must be same
as in the datafile. Frames are allowed to overlap.
If the isotope is specified, the correction for physical decay is at first
removed, then PET framing is simulated, and after that the framed data
is decay corrected again, based on the frame start time and length as is
the normal procedure when collecting PET image data.
Verify that time units are correct when using this possibility.
