# dyco apply-batch Remove lags listed in an existing `tlag_results.csv`. Detects nothing — it reads the numbers another run produced and shifts columns by them. Step 2 of the two-step route, after [`dyco pwb-batch`](pwb-batch.md). Also available as the standalone `dyco-apply-batch`. `--scalar LABEL:column` here reads the lag recorded under `LABEL` and applies it to `column`, so one gas's detected lag can be removed from another gas's data. ## All options ```{eval-rst} .. argparse:: :module: dyco.apply_tlag :func: _build_parser :prog: dyco apply-batch ```
