save_yaml

The module saves the paths provided as arguments to an output YAML file, provided after -o option.

If the outputs should be saved, the data should be converted via env-data module.

The YAML is human readable and fits to the purposes of saving a small data samples, such as fit results or small histograms or graphs.

The module is similar to the modules save-pickle and save-root.

Positional arguments

• paths – define paths to save

Options

• -o, --output – define output file name

• -v, --verbose – define verbosity level

Examples

Write the data, collected in the ‘output’ to the file ‘output.yaml’:

./gna \
    -- gaussianpeak --name peak --nbins 5 \
    -- env-data -c spectra.peak output '{note: extra information}' -vv \
    -- env-print -l 40 \
    -- save-yaml output -o output.yaml

In this example we have reduced the number of bins in order to improve readability of the ‘output.yaml’.
