The tool is designed so that it can be used for single or batch operations when datasets are added to both "Datasets to concatenate" and "Dataset > Insert dataset". Example of a batch operation: there are multiple input datasets to merge into multiple output datasets. However, for your single operation usage, try this method instead:
- Datasets to concatenate = add just one of the datasets
- Dataset, click on "Insert dataset" = add just one of the other datasets
- Repeat step 2 until all four are added individually
- The output will be one dataset with all four datasets merged. Use this merged output with downstream tools.
If you instead add all four datasets in step 1 (only), then an individual job is launched per dataset. This effectively creates four distinct new datasets with the each of the original single dataset's content (no dataset with merged/concatenated output is created).
Hope this clears up the usage for the tool! Jen, Galaxy team
