Calculate the slope of pixel TACs in dynamic PET image.
Slope is calculated between given start and end times (min).
Static image containing the slope value of each pixel TAC is written.
Usage: imgslope [Options] imgfile starttime endtime slopefile
Options:
-median
Instead of LSQ regression line, the slope is determined as median
of slopes between any two data points.
-sign
Change the sign of slopes.
-noneg
Pixels with negative slope (optionally after sign change) are set
to zero.
-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
