The header section of the krakentools beta_diversity.xml output file embedded the galaxy directory and It affects the file parsing in the downstream. Therefore, I made the simple patch by updating this wrapper. My colleague in Australia is submitting a workflow containing this tool to the workflowhub soon. I just patched the wrapper by adding the element_identifier to each input file.

Here's the screenshot of the beta_diversity output

Many thanks,

We need a bump of the version.

Wondering:

• should the output be tabular
• so we want to have more output assertions?

I believe you refer to the wrapper version not the tool version. I will bump the beta_diversity wrapper version up.

Re:

• should the output be tabular
  The output format is defined as txt in the wrapper not tabular
• so we want to have more output assertions?
  any suggestion? can you clarify what other outputs should be included in the test unit.
