-* `09-MergeBatchSites` is a cohort-level workflow, so it is run on a `sample_set_set` containing all of the batches in the cohort. You can create this `sample_set_set` while you are launching the `09-MergeBatchSites` workflow: click "Select Data", choose "Create new sample_set_set [...]", check all the batches to include (all of the ones used in `03-TrainGCNV` through `08-FilterBatchSamples`), and give it a name that follows the **Sample ID requirements**.
+* `09-MergeBatchSites` is a cohort-level workflow, so it is run on a `sample_set_set` containing all of the batches in the cohort. Navigate to the Data tab of your workspace. If there is no `sample_set_set` data table, you will need to create it. To do this, select the `sample_set` data table, then select (with the check boxes) all of the batches (`sample_set`) in your cohort. These should be the `sample_sets` that you used to run steps `03-TrainGCNV` through `08-FilterBatchSamples`. Then click the "Edit" icon above the table and choose "Save selection as set." Enter a name that follows the **Sample ID requirements**. This will create a new `sample_set_set` containing all of the `sample_sets` in your cohort. When you launch MergeBatchSites, you can now select this `sample_set_set`.
