Outputs

trasgu writes one CSV per fitted chunk and can combine those files into one final CSV.

Chunk files

Chunk files are written under the chunk work directory. By default this is .trasgu_<run> next to trasgu.yaml; it can be customized with output_dir.

fit_chunk_NNNN_MMMMM.csv

Where:

• NNNN is the zero-based chunk index.
• MMMMM is the configured chunk_size.

Example:

fit_chunk_0023_01000.csv

Columns

Chunk files contain three comma-separated values per row:

Column	Description
vine_id	Zero-based Chimera matrix ID.
n_parameters	Number of fitted copula parameters.
aic	Akaike information criterion for the fitted model.

Combined file

Use:

trasgu_combine

The default combined output is written next to trasgu.yaml:

fit_<run>.csv

The combined file includes a header:

vine_id,n_parameters,aic
