Update: I cannot get this “offline” option for metaphlan to work within Humann. I have tried the following formats:  
–metaphlan-options “–offline”  
–metaphlan-options “offline”

--metaphlan-options “-offline”

--metaphlan-options --offline

--offline

All of these lead to Humann to stop running. Is there some way around this within humann?

Additionally, I was able to fix this error for metaphlan by downloading the vJan25 Chocophaln database, but these are not the same files used by Humann. Could you please provide the link for the updated chocophlan database for humann? I work on an HPCC so the `humann_databases --download` function does not work for me. Thank you!
