To be able to run multiple sample data sets in batch mode, the user must initially make a copy of the template workflow, specify a Result Metadata Table and save the copy of the workflow in the Navigation Area before running it.
- Select the workflow Type among Multiple Species in the toolbox, right-click on the name and choose the option Open Copy of Workflow (figure 10.27).
- This opens a copy of the workflow in the view area of your workbench. Double click on the green tile representing the Result Metadata Table input file (highlighted in red in figure 10.28).
- It opens a window where you have to specify the Result Metadata Table you created for this particular workflow (figure 10.29). Click on Finish.
- Save you workflow in your Navigation Area.
- You can now click on the button Run at the bottom of the copy of the workflow in the View Area (highlighted in red in figure 10.30).
- Check the option Batch (highlighted in red in figure 10.31) before selecting several items (samples or folder(s) of samples) to be analyzed. Click Next.
- The next wizard window gives an overview of the samples present in the selected folder(s). Choose which of these samples you actually want to analyze in case you are not interested in analyzing all the samples from a particular folder (figure 10.32).
- In the third wizard window, you can see that the Result Metadata Table you specified earlier is already selected. Check that it is indeed the Result Metadata Table you intended to use and click Next.
- The rest of the workflow is similar to the one described in the How to run the Type Among Multiple Species workflow for a single sample section. Refer to this section to understand what parameters can be set, and which outputs are generated.
- In the last Result Handling window, we recommend saving the results in separate folders.
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.
