# Protocol Output

The *protocol_output* attribute is an object that will inform the client how to display information to the user *after* executing the protocol.

### dynamic_description

**usage: *optional* - datatype: *string***

The `dynamic_description` attribute is used to give an overview of what the protocol is analyzing. The `dynamic_description` can include references for the arguments in the protocol. The references will be replaced by the variables, collections, or values selected for the argument.

```
"dynamic_description": "Give an overview of the analysis with ARGUMENT_VALUE(argument_name)[ prefix text :: suffix text ]."
```

### export

**usage: *required* - datatype: *array***

`export` is an array which contains `method`-specific strings for the rendering of stock visualizations. The standard export for a `tag-comparison` method would include `tag-tag` and `numeric-tag`, while a `numeric-comparison` method would include `numeric-tag` and `numeric-numeric`.

```
"export": [
  "tag-tag",
  "numeric-tag",
  "numeric-numeric"
]
```

### visualization

**usage: *required* - datatype: *array***

The `visualization` attribute contains objects to customize the rendering of protocol results. The `visualization` attribute can include references for the `arguments` in the protocol or to display entity count placeholders. The references will be replaced by the variables, collections, or values as selected for the argument. There are also a number of descriptor types and options to adjust decimal places or graphic coloring. See the [Protocol Visualization Reference](https://tagbio-developer-docs.document360.io/docs/protocol-visualization-reference) for more details.

```
"visualization": [
  {
    "visualization_type": "numeric-tag",
    "descriptors": [
      {"focus-mean": "Average value of 'COLLECTION_PLACEHOLDER: VARIABLE_PLACEHOLDER' for cases in the focus  cohort ARGUMENT_VALUE(argument_name) (FOCUS_COUNT_PLACEHOLDER entities)"},
      {"background-mean": "Average value of 'COLLECTION_PLACEHOLDER: VARIABLE_PLACEHOLDER' for all cases (BACKGROUND_COUNT_PLACEHOLDER entities)"}
    ],
    "digits": 2
  }
]
```
