# ManualSigmas - ComfyUI Built-in Node Documentation

> The ManualSigmas node allows you to manually define a custom sequence of noise levels (sigmas) for the sampling process.

The ManualSigmas node allows you to manually define a custom sequence of noise levels (sigmas) for the sampling process. You input a list of numbers as a string, and the node converts them into a tensor that can be used by other sampling nodes. This is useful for testing or creating specific noise schedules.

## Inputs

| Parameter | Description                                                                                                                                                                                 | Data Type | Required | Range                                        |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | -------------------------------------------- |
| `sigmas`  | A string containing the sigma values. The node extracts all numbers from this string, including decimals and negative values. For example, "1, 0.5, 0.1" or "1 0.5 0.1". Default: "1, 0.5". | STRING    | Yes      | Any comma- or space-separated numeric values |

Note: This node is marked as experimental.

## Outputs

| Output Name | Description                                                                       | Data Type |
| ----------- | --------------------------------------------------------------------------------- | --------- |
| `sigmas`    | A tensor containing the sequence of sigma values extracted from the input string. | SIGMAS    |
