Tools for processing TAC files

Note that most of the listed applications work with several TAC formats, usually at least with DFT and PMOD files.

Editing TACs

Combining the regions from two DFT files into one file: tacadd
Catenating TACs, e.g. for combining early and late measurement data: taccat
Removing overlapping samples: dftrmovl
Extracting specified x (sample time) interval from the TACs: taccut, or specified y (concentration) interval: taccuty
Extracting all or selected TTACs from file: tacsplit and tacadd
Decay correction: tacdecay and tactime
Manual time delay correction: tactime
Deleting selected regions from a set of TACs: tacdel, or deleting TACs that have missing values: tacdelna
Printing or setting the PET time frames of regional TACs: tacframe
Adding weights to a DFT (preferably) or other TAC file: tacweigh
Thresholding and removing negative concentrations in DFT files: dftrmneg

Listing the regional TTACs contained in a DFT file: taclist
Listing the maximum value inside one or several DFT and other TAC files: tacrange and tacpeak
Listing the sample time range inside one or several TAC files: tacrange
Changing the region names inside TAC file: tacren, dftvncor, and dfthncor
Changing the study number inside DFT file: tacstudy
Sorting regional TACs inside TTAC files by name of region or by sample time: tacsort
Setting or conversion of calibration and time units in TAC file: tacunit
Removing the comments inside TAC files: rmcmnts
or in bash: sed '/^#/ d' < inputfile.dat > outputfile.dat

General TAC file format converter: tacformat
Converting DFT files to result file format: dft2res.
TAC data in CSV and TSV formats can be transposed with csvtrps.
Converting blood and plasma data files into Hammersmith format and back: dft2if, if2dft
Converting tissue data files into Hammersmith format and back: dft2idwc, idwc2dft
Converting DFT file into HTML table format for viewing in web browsers or importing to Excel: dft2html
Convert regional time-activity curve (TAC) data from GEMS Xeleris to DFT format: xel2dft
Convert TTAC data from Vinci to DFT format:
save TACs as *.cpt files in Vinci, and convert CPT format to DFT using cpt2dft
Convert TTAC data from Amide *.tsv files to DFT format: tsv2dft
Convert TTAC data from PPET *.tac files to DFT format: ppet2dft
Converting DFT file into RFIT 4.4 format: dft2rfit
Dynamic or parametric polar map can be converted to/from DFT file using programs pm2dft and dft2pm

Averaging regional TACs inside one file: dftavg and tacmean
Average of regional TACs from a list of studies: avgttac
Weighted average of all TACs ("head curve"): dfthead
Performing simple arithmetic operations for regional TACs: taccalc
Subtracting a reference region TAC from other TACs: dftbound
Calculation of sample mean over time: dftlevel, or mean weighted by time frame lengths: dftinteg with option -avg
Calculation of TAC AUC: dftinteg
Correction of recovery and spill-over in myocardial TACs: heartcor
Search time when concentration decreases below certain percentage of peak concentration: dftpeak
