dftcalc 1.4.9 © 1999-2014 by Turku PET Centre
Make arithmetic calculations with PET time-activity data in DFT or PMOD
format, see
http://www.turkupetcentre.net/analysis/doc/format_dft.html
Operations can be made between two data files or between one file and
a constant value.
Usage: dftcalc [Options] <datafile> <+|-|x|/> <value|2nd file> <output file>
Options:
-h, --help
Print this message and exit
-nt
Program does not mind if the time or calibration units do not match
--version or --build
Print software build information and exit
--silent
Program works silently, printing only warnings and error messages
--verbose
Program prints more information about what it is doing.
Example 1: Add two to all activity concentrations in data.dft
dftcalc data.dft + 2 sum.dft
Example 2: Subtract one curve from all curves in first data file
dftcalc cortex.dft - reference.dft bound.dft
Data file can have one or more data columns. Second file may contain only
one column or as many columns as the first data file (if the column number
is different, only the first one is used); data is interpolated, if necessary,
to the times of first file.
If the second file contains only one frame, the value from that
frame will be used for all the frames of the first file.
