# Analysis Launch with NovaSeq 6000Dx Application
When using the NovaSeq 6000Dx application, DRAGEN TSO 500 analysis starts automatically after sequencing completes.
{% hint style="warning" %}
The v2.6.2 app uses DRAGEN v3.11.2, which is not designed to be co-installed with earlier DRAGEN versions (e.g. v3.10.18 and below, v4.3.5 and below). When launching analysis after installing another NovaSeq 6000Dx app and its dependent version of DRAGEN (that does not support multi-version installation), the software may sporadically be unable to run.\
\
For example, users may encounter an issue if the following steps occur in order:
1. installation of the DRAGEN TSO 500 v2.6.2 app for NovaSeq 6000Dx and its dependent DRAGEN, v3.11.2
2. installation of the DRAGEN TSO 500 v2.6.0 app\* for NovaSeq 6000Dx and its dependent DRAGEN, v3.10.17
3. analysis is initiated using DRAGEN TSO 500 v2.6.2 app
\*or any other app requiring an incompatible DRAGEN version. See [Installation of 2.6.2 on Standalone DRAGEN Server](/tso500/dragen-tso-500-guides/dragen-tso-500-v2.6/getting-started/installation-of-2.6.2-on-standalone-dragen-server.md) for DRAGEN co-installation compatibility.
See Troubleshooting section for a workaround. [NovaSeq 6000Dx App Troubleshooting](/tso500/dragen-tso-500-guides/dragen-tso-500-v2.6/troubleshooting/novaseq-6000dx-app-troubleshooting.md)

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.bioinsight.illumina.com/tso500/dragen-tso-500-guides/dragen-tso-500-v2.6/launching-analysis/analysis-launch-with-novaseq-6000dx-application.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
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.
