pargroup

The module recursively selects parameters based on their status (free, constrained, fixed) and inclusion/exclusion mask. The list is stored in env.future and may be used by minimizers.

By default the module selects all the not fixed parameters: free and constrained.

Positional arguments

• name – defines parameter group name

• pars – defines the parameters to store

Options

• --ns – defines the namespace

• -m, --modes – take only parameters with specified property

  • choose one or more from: free, constrained, fixed

  • default: free constrained

• -x, --exclude – define parameters to exclude

• -i, --include – define parameters to include exclusively

• -a, --affect – select only parameters that affect the output

• -v, --verbose – define verbosity level

Examples

• Select not fixed parameters from the namespace ‘peak’ and store as ‘minpars’:

  ./gna \
      -- gaussianpeak --name peak \
      -- ns --name peak --print \
          --set E0             values=2.5  free \
          --set Width          values=0.3  relsigma=0.2 \
          --set Mu             values=1500 relsigma=0.25 \
          --set BackgroundRate values=1100 fixed \
      -- pargroup minpars peak -vv
  

• Select only fixed parameters from the namespace ‘peak’ and store as ‘minpars’:

  ./gna \
      -- gaussianpeak --name peak \
      -- ns --name peak --print \
          --set E0             values=2.5  free \
          --set Width          values=0.3  relsigma=0.2 \
          --set Mu             values=1500 relsigma=0.25 \
          --set BackgroundRate values=1100 fixed \
      -- pargroup minpars peak -m fixed -vv
