Hi! I am trying to run the example you have on the web page. [http://galaxy.biobakery.org/](http://galaxy.biobakery.org/) Sample\_LefSe\_Input --\>hmp\_aerobiosis\_small However I am retrieving this error in the step of running the LEfSe, which I do not know how to solve. I am new in LEfSe and trying to figure out how it works for some metabolomics and microbiota analysis. Thank you in advance. Kind regards.
