# Basic Extreme Extraction (+1)

## Basic Extreme Extraction


```yaml
# configs/extreme_analysis.yml

orcaflex:
  postprocess:
    linked_statistics:
      flag: true

      # Primary variable (extremes will be found for this)
      primary:
        object: "Mooring_Line_1"
        variable: "Effective Tension"

      # Linked variables (values at primary's extremes)
      linked:
        - object: "Vessel"
          variable: "Heave"
        - object: "Vessel"
          variable: "Pitch"
        - object: "Vessel"
          variable: "Roll"
        - object: "Vessel"
          variable: "X"

      # Statistics to extract
      statistics:
        - "Max"
        - "Min"
        - "TimeOfMax"
        - "TimeOfMin"
        - "LinkedValueAtMax"
        - "LinkedValueAtMin"

      output:
        format: csv
        directory: "results/extremes/"
```


## Multi-Object Analysis


```yaml
# configs/extreme_multi_object.yml

orcaflex:
  postprocess:

      # Analyze multiple primary objects
      groups:

              variable: "Pitch"
          linked:
            - object: "Hawser"
              variable: "Effective Tension"

      output:
        format: csv
        directory: "results/extremes/"
