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
     Suppress displaying anything except errors.
