Mixed Model Tool Issues

[ch728]

Started playing around with the mixed model tool a little. I noticed a couple of issues.

1. There is no way to specify a nesting of variables, only interaction. It is common to nest rep in location to make unique rep factor for example.
2. After running a model the results are shown with no header for the traits (see below) and there is no way to download the result.
3. The save button allows one to save the analysis in the database (models can be saved though); however, this doesn't seem to work yet as I get this error message when trying to save the analysis:

I understand this is a newer tool and under active development, just wanted to provide some (hopefully) useful feedback!

Hi Chris, do you have a location called [Computation] in the database? That's what the tool uses as location. Sometimes users delete this location because they think it is not useful

[lukasmueller]

There is a ticket for adding nested variables. I thought there was a download, if not we should definitely add that option and have proper headers.

I definitely deleted the Computation location. Can I simply add a location called Computation to fix this?

[lukasmueller]

Yes. It has to be called [Computation] (with the brackets) Maybe we should change this or prevent it from getting deleted. cheers Lukas

added issue #3927 to prevent computation location deletion. Pull request #3928.

[lukasmueller]

Let's make this issue about adding a header and the download. (nesting already has an issue.)

[ch728]

Okay, sounds good. I added the [Computation] location back and it fixed the issue with saving the analysis.

Closing this issue as a duplicate of #3997.
