Customize DFT file with this tool. dftweigh help you add or remove the frame weighting information to DFT file for parameter estimations.
TACs in DFT file are assumed to be corrected for decay. The relative weights are adjusted using a scan information file (SIF), or TACs in DFT file (volume weighted average of all regions or given region); in the latter case the units in DFT file must be set correctly.

Note that absolute weights cannot be calculated. Relative weights are scaled so that average weight is 1.0.

Usage: dftweigh [Options] <DFT file> [SIF file | Region name]
Options:
-rm
Existing weights are removed
-i=<Br-76|Cu-62|C-11|Ga-68|Ge-68|F-18|N-13|O-15|Rb-82>
Isotope, in case it is not found inside SIF file. Isotope is only needed when SIF file is used.
-L Weights are not calculated, but existing weights are printed on screen.
-sif=<Filename>
SIF data based on DFT file is written in given file.
-moderate=<value>
Weights are moderated by adding (1/value)*max true counts to all counts, if (max trues)/value > (min trues). By default, value=100. You can set value to zero to apply full range of weights.
-wf
Weights are based only on frame length or sampling interval.
-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.
