dftslope 0.5.1 © 2004-2011 by Turku PET Centre
Program for finding the highest slope of TAC(s) in a DFT file.
The intercept with x axis can be used as an estimate of tracer appearance
time, and can be used optionally (by specifying name for new DFT file) to
correct sample times so that the curve(s) start to rise at zero time.
Usage:
dftslope [Options] <DFT file> <Nr of points for slope> [new DFT file]
Options:
-xic
Reports the average intercept with x axis (default)
-slope
Reports the highest slopes and their average
-rmbkg
Sample values before appearance time are set to zero
-rise=<time>
TAC(s) in new DFT start to rise at specified sample time (by default 0)
-o=<filename>
Reported values are written in specified file
-h or --help
Print this message and exit
--version or --build
Print software build information and exit
--silent
Program works silently, printing only error and warning messages
--verbose
Program prints more information about what it is doing.
User should set the number of points for slope calculation, based on
visual inspection of the data. If number is set to 0, then program tries
to set the number automatically.
