The Transform node allows you to select and visually preview the results of
transformations before applying them to selected fields.
Example
stream = modeler.script.stream()
typenode = stream.findByID("id42KW3MSA94B")
node = stream.create("transform", "My node")
stream.link(typenode, node)
node.setPropertyValue("fields", ["Age", "K", "Na"])
node.setPropertyValue("formula", "Select")
node.setPropertyValue("formula_log_n", True)
node.setPropertyValue("formula_log_n_offset", 1)
node.run([])
