Cloning folder that is found in the example data contains two sequences () and four folders (). If the Batch checkbox is checked and the Cloning folder is selected for an analysis, then after clicking on the button labeld Next an overview of the batch units like that in figure 7.6 is shown.
The batch overview lists the batch units on the left and the contents of the selected batch unit on the right.
In this example, the two sequences are defined as separate batch units because they are located at the top level of the Cloning folder. Of the four subfolders of the Cloning folder (see figure 7.5), three are listed in this view. In each of these subfolders, any data elements that the analysis could use as input will be used unless action is taken at this point to exclude some of these. Clicking on the name of each batch unit on the left hand side will initially cause the display of all the data elements that can be used by the analysis tool. These elements will be used as a single set of input for a particular analysis run. So, for example, in figure 7.6, all the elements in the subfolder
Cloning vector library that will be included as part of a single analysis run shown on the right-hand side of the dialog.
Note that the fourth subfolder of the Cloning folder, the
Enzyme lists folder, is not listed as a batch unit. It is because it does not contain any data that can be used by the tool being launched.
There are three ways to refine the data elements that should be included in a batch unit, and thereby get taken forward into the analysis.
- Use the fields labeled Only use elements containing and Exclude elements containing at the bottom of the batch overview This refinement is done based on data element names. for example, only paired reads might be desired for the analysis, in which case, putting the text "paired" into the Only use elements containing field might be useful.
- Remove a whole batch unti Right-click on the batch unit to be removed and choose the option Remove Batch Unit.
- Remove a particular data element from a batch unit Right click on the element of a batch unit to be removed and choose the option Remove Element. This can be useful when filtering based on name, described in the first option, cannot be used to refine the batch units specifically enough.
