interpol 2.6.1 © 1993-2013 by Turku PET Centre

Program for linear (dot-to-dot) interpolation and integration of time- activity curves (TACs). Usage: interpol [Options] <datafile> [output file] Options: -y or -i or -ii TACs are interpolated (-y, default), integrated (-i), or the 2nd integral (-ii) is calculated. -X=<x1;x2;...> or -C=<start;stop;step> or -F=<xfile> The sample times for interpolated or integral TACs can be specified with these options; if none of these is given, the sample times of the original datafile are used. Definite sample times can be given after -X; regular sample timing can be specified using option -C; with -F the sample times can be read from any DFT file. -A=[t] Input TACs are interpolated and integrated with sample (0,0) or (t,0) as their first measurement points. -0=<y|F> Input TACs are interpolated and integrated with sample (0,y) added if TAC starts later than at zero time. With option -0=F the first existing sample value is used as y value. -header=<Yes|no> Descriptive title lines (if header information is available) can be included (default), or not included. -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. Input data is considered to be non-framed even if it contains frame start and end times; if necessary, frame mid times are used. The interpolated or integrated values are calculated exactly at the specified sample times, except when the start and end times of PET frames are given with -F=<xfile>; then the time frame average values or integrals at the frame mid time are calculated. If output filename is not specified, the results are written to stdout. Output is written in same TAC file format as the input file; http://www.turkupetcentre.net/petanalysis/format_tpc_dft.html See also: dftinteg, fr4sim, dftframe, ainterp, dftcut, extrapol, dftsuv Keywords: DFT, tools, modelling, simulation, AUC, interpolation This program comes with ABSOLUTELY NO WARRANTY.
