 The 99% in the circle mean that, according to our suggestion engine, 99% of the input sequences match the reference sequence of the selected dataset. The message in a blue alert box may show that there are other datasets that are also compatible with the input sequences. To see them, click "Change reference dataset" and it will navigate you to the dataset page.
 
 On the dataset page you can see the list of all existing datasets. The subset of suggested datasets is emphasized, while the rest of the datasets are faded. You can stick to the suggested dataset or select the one you think is more appropriate for your data.
 
-On that page You can also find some information about dataset in the "Summary" tab. As well as a history ry of changes in the "History" tab.

 Advanced users may override dataset files on the "Customize" tab. This requires good understanding of [Input files](../input-files) and of the [Nextclade algorithms](../algorithm).
 
 ### 3. Run the analysis
 
-Once you are happy with the set of sequences and with the selected dataset, click "Run" to start the analysis. Nextclade will then automatically navigate you to the [analysis results page](analysis-results-table).
