Hi! We are trying to use the command humann2_associate, and our output files are empty besides the first line. Our error file says only the following:
NOTE: Unable to compute Kruskal-Wallis with feature: VALSYN-PWY: L-valine biosynthesis
Performing Kruskal-Wallis analysis vs. metadatum: STATUS
NO FDR SIGNIFICANT ASSOCIATIONS
There should be significant associations given the amount of data. Why is this not working? Is there a reason why it is unable to perform the test?
