[Seqan-dev] Problem with KNIME "Input Files" node

["Ivan Protsyuk" <ivan.protsyuk@embl.de>]

Hi everyone,

 

I'm wondering if it's possible anyhow to use "Input Files" node (from GenericKnimeNodes) with no input files. In my workflow, I use several of nodes of this kind, and the logic of the workflow implies that some input datasets can be empty. However, "Input files" seems to be not usable if I don't select any file. Are there any alternatives to this?

 

My current workaround is giving a stub-file with a predefined name that stands for an empty dataset. However, it’s rather non-intuitive for other people when I share workflows with them.

 

Kind regards,

Ivan Protsyuk
