I'm assessing LabKey for our institution, and I'm having difficulty with fairly simple (I think) tasks.

First, I'm following the tutorials to load assay data. My assays have

- ParticipantId
- Visit ID
- Date

as primary key. I have managed to load the assay data with no trouble, and the data looks correct. The problem arises when I try to copy the data to a study. From the assay batch page, I select my assay run, and click copy to study. The data passes validation, and there are no errors when I then select copy to study again. However, the study has no data. The column headers are:

- Container   
- Label   
- Description   
- Description Renderer Type

which is not correct. If I try to reimport the data, it says that my rows have already been loaded. The study navigator also seems to know about the dates in my data. I have loaded a separate dataset (different assay) in exactly the same way, without these difficulties. Any idea what might be the problem?

Second, our data is managed by an external database. I need to have a way to periodically reload the data from file, preferably without losing all of the reports I've already set up. I have two different types of data: a regular dataset (added through manage datasets), and several assays. These aren't really assays per se, but they require 3 primary keys. I need to replace this data, rather than add to it.

It seems that I need to set up a data pipeline: https://www.labkey.org/Documentation/wiki-page.view?name=pipelineSetup
The directions say to do the following:

- Go to Admin > Go to Module > Pipeline.
- Now click Setup.

However, I can't find Setup anywhere on the page!

Additionally, I tried to export/reimport a study, and my assay dataset was not repopulated correctly.

Am I using assays incorrectly?
