Running multimodal workflows in batch using metadata

In order to run the workflow in batch, metadata must be provided to describe which DNA and RNA reads belong together.

See https://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=Running_workflows_in_batch_mode.html for details on batch analysis, https://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=Metadata.html for general information about metadata, and https://resources.qiagenbioinformatics.com/manuals/clcgenomicsworkbench/current/index.php?manual=Importing_metadata.html for how to import a metadata table.

Metadata can easily be supplied from an Excel spreadsheet or CSV file. A minimal spreadsheet should contain the start of the file names and a column containing the sample information:

Fastq Sample
DNA-S1 S1
RNA-S1 S1
DNA-S2 S2
RNA-S2 S2

Start the workflow normally, but remember to tick batch twice - once when selecting DNA reads (figure 15.9), and again when selecting RNA reads (figure 15.10).

Metadata can be chosen in the "Configure batching" dialog (figure 15.11).

The next dialog will show how the batching will be performed (figure 15.12).
