Dataset not run by LefSe in galaxy at second step. b) LDA effect size (LefSe)

Hi, my MetaPhlAn output is not running by LeFse (Galaxy). The first [A) Format Data for LEfSe] step is running but the next [B) LDA Effect Size step is not running. It reverts the following error:

Number of significantly discriminative features: 51 ( 51 ) before internal wilcoxon
/galaxy_venv/local/lib/python2.7/site-packages/rpy2/rinterface/ RRuntimeWarning: Error in (function (file = “”, n = NULL, text = NULL, prompt = “?”, keep.

Why is it happening? Here’s my file MetaPhlAn output file: lefsetobiobakery.txt (41.7 KB)
