**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](http://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](https://help.galaxyproject.org/t/correcting-errors-with-ncbi-fcs-gx-foreign-contamination-screening-assembled-genomes/15987)

Hope this helps or that everyone saw the other post already! 🚀
