# samples attributes clear

Remove all of a sample's custom attributes

## Synopsis

```shell
omics workbench samples attributes clear SAMPLE_ID
  [--force]
  [--namespace=STRING]
```

## Description

Remove all of a sample's custom attributes, leaving it with `{}`.

{% hint style="warning" %}
This cannot be undone. The command prompts for confirmation unless `--force` is passed.
{% endhint %}

Only custom attributes are removed. The sample's pedigree — its sex, affected status, family and parentage — and its phenotypes are stored separately and are left untouched.

To remove some attributes but keep others, use [samples attributes set](/products/command-line-interface/reference/workbench/samples-attributes-set.md) with a document containing only the ones to keep.

## Examples

Clear a sample's attributes, confirming at the prompt:

```shell
omics workbench samples attributes clear HG002
```

Clear without prompting, for use in a script:

```shell
omics workbench samples attributes clear HG002 --force
```

## Positional Arguments

### `SAMPLE_ID`

The ID of the sample. Sample IDs can be retrieved from the [samples list](/products/command-line-interface/reference/workbench/samples-list.md) command.

## Flags

### `--force`, `-f`

Do not prompt for confirmation.

### `--namespace`=`STRING`

An optional flag to define the namespace to connect to. By default, the namespace is extracted from the user's credentials.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.omics.ai/products/command-line-interface/reference/workbench/samples-attributes-clear.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
