Update
Apologies! I forgot to link this back. The solution here is to update the tutorial workflow, or your own workflow, or your direct run, to use the most current version of the NCBI FCS tool when working a UseGalaxy.org or any other server where you may be having problems.
We might be able to correct the older version but it isn’t a priority. Full details are in here if you aren’t sure how to do this (screenshots, FAQs) → Correcting errors with NCBI FCS GX Foreign Contamination Screening assembled genomes
Hope this helps or that everyone saw the other post already!
