Galaxy workflow if-else issues

Hi, I’m new to Galaxy workflow, and I have a problem with Galaxy workflow. Usually, we use GIE to customize tools to handle our data. In there, we can use the if-else branch to decide the next step based on the results in previous steps.

May I ask if the Galaxy workflow can achieve the same if-else function? Because I just can connect the tools when using the workflow. Thanks!

Check out the expression tools, there is a training that uses them here: https://training.galaxyproject.org/training-material/topics/galaxy-ui/tutorials/workflow-parameters/tutorial.html
