# Re-Launch Analysis

When an analysis fails or doesn't meet quality standards, you can schedule a new analysis using the original input or different inputs.

* In cases where the analysis failed to successfully complete in BaseSpace Sequence Hub, you can relaunch the analysis using the original input.
* In cases where the analysis did not meet quality standards, you can exclude or include data and relaunch the analysis using only data that passed QC.

Requirements:

* If you are scheduling an analysis workflow that uses more than one sample as input (eg, Tumor Normal), all existing biosamples must have been imported from same original biosample workflow file.
* The biosample workflow must be imported using the account that owns the biosamples. If the biosample workflow is uploaded to an account that does not own the biosample, the biosamples are added to the account as new biosamples.

1. \[Optional] Exclude or QC fail any of the following resources. Excluding a resource also excludes any downstream data produced by the resource. For information about changing QC, see [Manual QC](https://help.connected.illumina.com/basespace/automate/manual-qc).
   * Biosample
   * Library
   * Pool
   * Lane
   * Run
   * FASTQ Dataset
2. Add the following information to a new biosample workflow file.
   * Biosample Name
   * Analysis Workflow
   * \[Optional] Analysis Group
   * \[Optional] Sample Label
   * \[Optional] Delivery Mode

{% hint style="info" %}
All template columns must be present in the biosample workflow file, but the Default Project cannot be changed using a biosample workflow. If the biosample does not exist in the specified project, BaseSpace Sequence Hub creates a new biosample in the project. For information about changing the default project for a biosample, see [Change Default Project](https://help.connected.illumina.com/basespace/biosamples/manage-biosamples#change-default-project).

# Agent Instructions: 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:

```
GET https://help.connected.illumina.com/basespace/analyze/relaunch-analysis.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
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.
