# Troubleshooting "Conflict" errors at the end of MiSeq runs
**Background**
MiSeq Control Software may display a Notification message stating "Conflict" during or shortly after the final cycle of a MiSeq run. Although this error typically prevents post-run analysis from starting automatically, it does not impact overall run performance.
A potential cause of this error is that the sample sheet is not present in the selected directory at the start of secondary analysis. This can occur if the sample sheet is selected from a temporary network location or USB flash drive at run start, and the sample sheet is no longer available in the temporary network location or the USB flash drive has been removed has been removed by the time secondary analysis begins.
To resolve this issue, requeue the analysis in Local Run Manager with a new sample sheet. For instructions to do so, please review the Illumina Knowledge Article [How to requeue and import run data for reanalysis with Local Run Manager](/instrumentation/general/instrumentation-general-reference_material-list/000001324.md).

## 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://knowledge.illumina.com/instrumentation/miseq/instrumentation-miseq-troubleshooting-list/000008345.md?ask=&goal=
```
`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.
