Options

-g, --group – define parameter groups to work with

--free – set parameter free

--variable – set parameter as not fixed (not to use with ‘fix’/’fixed’ option)

--fix, --fixed – set parameter as fixed (not to use with ‘variable’ option)

--randomize-constrained – randomize normally distributed constrained parameters

--randomize-free – define width to randomize normally distributed free parameters accroding to

--pop – restore the previous value (not to use with ‘push’ option)

--push – push the value and backup the previous one (not to use with ‘pop’ option)

--sigma – set sigma value (not to use with ‘relsigma’ option)

--relsigma – set relative sigma value (not to use with ‘sigma’ option)

-v, --verbose – define verbosity level

Example

Set the parameters in the namespace ‘peak’ free:

./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 fixed \
        --set BackgroundRate values=1100 relsigma=0.25 \
    -- pars peak --free --variable -vv \
    -- ns --name peak --print
