From a few tests and looking at the Galaxy source code, it looks to me
Hi everyone, The Galaxy API is a great way to interact with a Galaxy server and I've been using it to run workflows (supported by the blend4j library, since I'm working on a Java project). Recently, I ran into a challenge with the workflow step IDs. When retrieving the metadata of a Galaxy workflow (using the API and blend4j), the order of the workflow step IDs appears to be random (or at least, not what I expected). This makes it complicated to specify parameters when you run a workflow via the API, because the step ID and parameter name normally are a nice way to pick the parameter you want to set (blend4j method: WorkflowInputs.setStepParameter). Is is possible to determine which step ID is assigned to - for example - the second workflow step? like the workflow steps are sorted according to their position in the workflow editor (in ascending order of sqrt(sqr(position.x) + sqr(position.y))). When storing the workflow in the database, the ID field for each step is assigned a unique unpredictable number (by SQLAlchemy or the database?). But in addition to the ID, there is also a nice order_index field, which contains the indices in the expected order! Would it be possible to add the order_index field to the API and would that solve the step order issue? Cheers, Freek ------ Freek de Bruijn Scientific programmer | VU University medical center
