dftscale 0.2.2 © 2006-2009 by Turku PET Centre
Adjust two TACs into the same level to make visual comparison easier,
or adjust the TAC peak to specified value.
Datafiles must contain only one TAC.
Usage 1: dftscale [Options] <Datafile1> <Datafile2> <Scaled datafile2>
Usage 2: dftscale [Options] <New peak value> <Datafile> <Scaled datafile>

--verbose
Program prints more information about what it is doing.
The procedure for adjusting one TAC to another is:
1. interpolate data2 to sample times in data1
2. calculate AUC1 and AUC2 between first and last sample time
3. calculate the scale factor as AUC1/AUC2
4. multiply data2 with the scale factor, and save the file.
The procedure for adjusting TAC peak is:
1. find the maximum TAC value
2. calculate the scale factor as peak/maximum
3. multiply data with the scale factor, and save the file.
