Batch mode is activated by clicking the Batch checkbox in the dialog where the input data is selected (figure 9.6).
Unlike launching a single task, you can select a folder as well as, or instead of, individual data elements for the analysis.
A batch unit is the set of data that will be used as a single input set for a given run of an analysis. A given batch unit can consist of one or more data elements.
If a folder is selected as input to a batch analysis, each folder or data element directly under that folder will be considered a batch unit. This means:
- Each individual data element contained directly within the folder is a batch unit.
- Each subfolder directly within this folder is a batch unit, so all elements within a given subfolder will be considered as single input for the purposes of the analysis.
- Elements in any more deeply nested subfolders (e.g. subfolders of subfolders of the originally selected folder) will not be considered for the analysis.
