Hello, I’m trying to run a suite (u-cf771) on ARCHER2 that I have copied from a suite that was previously running on NEXCS. The postproc is failing due to “Bad optional configuration key(s): archer2”. Could you advise? Thank you! Lauren ---

Hi Lauren, Your suite is set up with an optional configuration override file for postprocessing settings. See `~/roses/u-cf771/app/postproc/opt/rose-app-archer.conf`. You will need to create a similar file called `rose-app-archer2.conf`. You will then need to change the `means_cmd` to: `means_cmd=ncra --64bit_offset -O` Regards, Ros. ---

Hi Ros, Thank you! The postproc has now succeeded except for cice due to a missing ncrcat path. What should this be? Thank you, Lauren ---

Hi Lauren, The path for `ncrcat` should be blank as it is added into the environment when the `nco` module is loaded. You’ve got `/work/y07/shared/umshared/nemo/nco/nco-4.4.7/bin` in the `job.err` file. I’m not sure why that is as I can’t see your `/work` directory on ARCHER2. It’s obviously not picking up the override correctly. Setting `ncrcat_path` to blank in the GUI will probably fix it, but you may get other problems if that override isn’t working. If you give me read access to your directories on ARCHER2 I can take a look. ```auto chmod -R g+rX /home/n02/n02/ chmod -R g+rX /work/n02/n02/ ``` Cheers, Ros. ---

Hi Lauren, I’m rather confused as to why you had that postproc `archer2` opt config error at the beginning now because it’s not using an optional override file for postproc - the settings in the namelist over on ARCHER2 are the ones in the GUI hence the path issue. Change the following two variables in the GUI and hopefully that will fix the problem. - `means_cmd` to `ncra --64bit_offset -O` and - `ncrcat_path` to blank. Regards, Ros. ---

Hi Ros, That’s sorted it, thanks very much! Lauren ---
