Batch filtering and counting
At the bottom of the dialog shown in figure 8.3, the Workbench counts the number of files that will be run in total (92 in this case). This is counted across all the batch units.In some situations it is useful to filter the input for the batching based on names. As an example, this could be to include only paired reads for a mapping, by only allowing names where "paired" is part of the name.
This is achieved using the Only use elements containing and Exclude elements containing text fields. Note that the count is dynamically updated to reflect the number of input files based on the filtering.
If a complete batch unit should be removed, you can select it, right-click and choose Remove Batch Unit. You can also remove items from the contents of each batch unit using right-click and Remove Element.
