<div dir="ltr">I'm not exactly sure what your goal is. If you're trying to write some kind of a UI that builds a pipeline based on some options (or some such), then what you're doing is pretty much it. You might want to look at the source code for some of the kernels. The info kernel is a bit of a mess, but does this kind of thing. You might also have a look at PipelineManager, which is what we use internally to build pipelines from a specification.<div><br></div><div>That said, no matter what you're doing, the general procedure is to build a pipeline, then prepare and execute it.</div><div><br></div><div>Hope that helps,</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, May 16, 2018 at 9:06 AM, Odd Ragnar Lydersen <span dir="ltr"><<a href="mailto:Odd-Ragnar.Lydersen@powel.no" target="_blank">Odd-Ragnar.Lydersen@powel.no</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
