## Features to Note for this Release

This release of the BaseSpace Clarity LIMS integration package provides:

* API-based integration between NovaSeq instrument and BaseSpace Clarity LIMS.
* Support for asymmetric sequencing read length.
* Support for the newly launched SPrime (SP) flowcell.
* Support for long read sequencing (2x250) on SPrime (SP) flowcell.
* Updated workflow (NovaSeq 6000 v3.0) delivered directly from PCWP v1.2
* Direct file and information exchange between Clarity LIMS and NovaSeq Control Software (NVCS) via API includes the following:
  * From LIMS to NVCS:
    * Sample sheet generated on LIMS to NVCS
    * Run recipe generated on LIMS to NVCS
  * From NVCS to LIMS:
    * Run status updates (RunStarted, RunCompletedSuccessfully, RunEndedByUser, RunErroredOut) from NVCS to LIMS
    * Run metrics information from NVCS to LIMS

## Known issues

* In the run metrics payload that NVCS v1.6.0 sends to Clarity LIMS:
  * ReadsPF information is currently not available. (This will be fixed in the upcoming NVCS release.)

## 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://help.claritylims.illumina.com/instruments-and-integrations/other-release-notes/novaseq6k-api-v3.2.1-release-notes.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.
