How to know unaligned reads when runing Metaphlan4

I saw the output csv did not include how much percentage of unaligned reads? just designed k_bacteria is 100%, so, is there any way to see the unaligned percentage for each sample after I finished running the metaphlan4. (I saw the value was printed on the screen after running,but I didn’t record it at that time).

Try to add the flag --unclassified_estimation to your metaphlan run
