Hi all - I'm creating a tool in Galaxy that takes as input several datasets for different variables. For each variable, I want to restrict the input to a single dataset. The docs, https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax, indicate type="data" needs to be set for a dataset from the current history to be available for input. When I do this, Galaxy displays the icon for Single Dataset, Mulitple Datasets, and Dataset collection.

I only want to give the option for Single Dataset. I tried include multiple="false", but that doesn't seem to have any effect. Is there a way to accomplish this?

multiple=false is the default setting and you can not hide "Mulitple Datasets, and Dataset collection". Nevertheless, this is not needed. If you tool only takes one dataset, e.g. multiple=false, than Galaxy will run this tool X times if the user have choosen X files instead of one. So on the end one tool run just consumes one file. Hope this helps, Bjoern
