Example of results obtained using the Type a Known Species (legacy) workflow
In this section, the Salmonella enterica sample sequence data (acc no ERR274480) was typed using a customized Salmonella enterica version of the Type a Known Species (legacy) workflow: the applied reference list only included Salmonella specific sequences, the MLST scheme was specified as Salmonella enterica and the created Result Metadata Table included only this particular data set.
Once the workflow analysis was performed on this single dataset, additional columns listing the analysis results (e.g., MLST, best matching reference and identified resistance genes) have automatically been added to the Result Metadata Table (figure 24.55). To ease the overview regarding applied analysis parameters, columns stating the workflow specified reference list, MLST scheme and resistance gene database have also been added automatically to the table.

Analyzing samples in batch will produce a large amount of output files, making it necessary to filter for the information you are looking for. Through the Result Metadata Table, it is possible to filter among sample metadata and analysis results. By clicking Find Associated Data () and optionally performing additional filtering, it is possible to perform additional analyses on a selected subset directly from this Table, such as:
- Generation of SNP trees based on the same reference used for read mapping and variant detection (Create SNP Tree).
- Generation of K-mer Trees for identification of the closest common reference across samples (Create K-mer Tree).
- Run validated workflows (workflows that are associated with a Result Metadata Table and saved in your Navigation Area).
Note that the tool will output, among other files, variant tracks. It is possible to export multiple variant track files from monoploid data into a single VCF file with the Multi-VCF exporter. This exporter is uploaded to the workbench when installing the Microbial Genomics Module. All variant track files must have the same reference genome for the Multi-VCF export to work.
