Hi,

I am trying to do the Rosie tutorial but haven’t been able to figure out how to configure it. I read that I should use the prefix [https://code.metoffice.gov.uk](https://code.metoffice.gov.uk) but am not sure how exactly to put this information in rose.conf, or where the rose.conf file should live (just somewhere in the path?).

Currently I get “cannot determine prefix location” errors, so need to set the prefix in order to continue with the tutorial.

I’m using Rose 2.0.1.

Thanks,  
Joe

I tried using the conf file

[rosie-id]  
prefix-location.u=[https://code.metoffice.gov.uk](https://code.metoffice.gov.uk)

but then get “settings not defined in site/user configuration”.

Note that the `rosie` command has not been well tested in Rose 2.  
For the moment we recommend using Rose 2019.01 if you need to use `rosie`.  
The [cylc wrapper script](https://github.com/cylc/cylc-flow/blob/master/cylc/flow/etc/cylc) (also used for running the `rose` and `rosie` commands) contains logic to support this.
