Hi all, I am trying to reproduce my old code [https://github.com/ribeiron/ScriptsChapter3/blob/main/Fig9\_b-g.ipynb](https://github.com/ribeiron/ScriptsChapter3/blob/main/Fig9_b-g.ipynb) and keep getting this error: FileNotFoundError: [Errno 2] No such file or directory: b’/g/data/ik11/outputs/access-om2-01/01deg\_jra55v13\_ryf9091\_easterlies\_up10/output1022/ocean/ocean.nc’ I noticed that the “easterlies down/up” experiments have changed location to cj50 since the last time I used them, but I was told that it should still be accessible through the cosima database (as per my code), as long as I have the gdata/cj50 location in my storage line when you open ARE/gadi\_jupyter. It was already there though, so I must need to update something else. Any leads? Thank you! ---

Just making sure: Are you a member of cj50 project on NCI? ---

Yes, it looks like there is nothing wrong with my membership. Still current. ---

It was already there though, so I must need to update something else. I’d guess that the COSIMA Cookbook database hasn’t been updated for the new location. @micael might be able to assist. ---

As a work around until the COSIMA database is updated (if that’s the problem), you could make your own database for these simulations by following [this tutorial](https://github.com/COSIMA/cosima-recipes/blob/main/Tutorials/Make_Your_Own_Database.ipynb). ---

I just tested accessing this data (which is here `/g/data/cj50/access-om2/raw-output/access-om2-01`) and the experiments with `easterlies` in the names still aren’t accessible from the main COSIMA database. Do we need to manually add them to the COSIMA database? @micael @aekiss ---

The indexing log seems to indicate that there are several experiments in that location with `easterlies` in the names that are in the database: ```auto Indexing: /g/data/cj50/access-om2/raw-output/access-om2-01/01deg_jra55v13_ryf9091_easterlies_down10 Indexing experiment: 01deg_jra55v13_ryf9091_easterlies_down10 Indexing: /g/data/cj50/access-om2/raw-output/access-om2-01/01deg_jra55v13_ryf9091_easterlies_up10_zonal Indexing experiment: 01deg_jra55v13_ryf9091_easterlies_up10_zonal Indexing: /g/data/cj50/access-om2/raw-output/access-om2-01/01deg_jra55v13_ryf9091_easterlies_up10 Indexing experiment: 01deg_jra55v13_ryf9091_easterlies_up10 Indexing: /g/data/cj50/access-om2/raw-output/access-om2-01/01deg_jra55v13_ryf9091_easterlies_up10_meridional Indexing experiment: 01deg_jra55v13_ryf9091_easterlies_up10_meridional ``` @adele-morrison Can you tell me if there are any experiments missing from this list? And are you able to access the experiments from the above list? ---

Hi Micael. Sorry I am back pestering you about this but I could use a closer look at the wind field of this experiment before I submit my work. I am trying to access experiment\_eup = ‘01deg\_jra55v13\_ryf9091\_easterlies\_up10’ and’01deg\_jra55v13\_ryf9091\_easterlies\_up10\_zonal’. They are both in your list, so that is odd. I still get this error when trying to access them: FileNotFoundError: [Errno 2] No such file or directory: b’/g/data/ik11/outputs/access-om2-01/01deg\_jra55v13\_ryf9091\_easterlies\_up10/output1032/ocean/ocean.nc’ These are the paths I have written down: master\_session = cc.database.create\_session(‘/g/data/ik11/databases/cosima\_master.db’) control = ‘01deg\_jra55v13\_ryf9091’ experiment\_eup = ‘01deg\_jra55v13\_ryf9091\_easterlies\_up10’ easterlies\_up\_zonal = ‘01deg\_jra55v13\_ryf9091\_easterlies\_up10\_zonal’ $plot anomalies for last 5 years of simulation: start\_time=‘2150-01-01’ end\_time=‘2159-12-31’ temp\_con = cc.querying.getvar(control,‘temp’, master\_session,frequency=‘1 monthly’,start\_time=start\_time, end\_time=end\_time) - 273.15 temp\_con = temp\_con.sel(yt\_ocean=lat\_slice).sel(xt\_ocean=lon\_slice).sel(st\_ocean=depth\_slice) temp\_con = temp\_con.load() temp\_up = cc.querying.getvar(experiment\_eup,‘temp’,master\_session,frequency=‘1 monthly’,start\_time=start\_time, end\_time=end\_time) - 273.15 temp\_upY = temp\_up.sel(yt\_ocean=lat\_slice).sel(xt\_ocean=lon\_slice).sel(st\_ocean=depth\_slice) temp\_upY = temp\_upY.load() temp\_up = cc.querying.getvar(easterlies\_up\_zonal,‘temp’, master\_session,frequency=‘1 monthly’,start\_time=start\_time, end\_time=end\_time) - 273.15 temp\_upX = temp\_up.sel(yt\_ocean=lat\_slice).sel(xt\_ocean=lon\_slice).sel(st\_ocean=depth\_slice) temp\_upX = temp\_upX.load() PS: I can try to build my own database as suggested by Adele, but because I just want to do a quick look that won’t even end up on the paper I was hoping I could just do it through the database. ---

Hi Natalia, The error message you are getting says it’s trying to open the files in `/g/data/ik11/outputs/access-om2-01/01deg_jra55v13_ryf9091_easterlies_up10`, but the files are actually in `/g/data/cj50/access-om2/raw-output/access-om2-01/01deg_jra55v13_ryf9091_easterlies_up10/`. Not sure why it’s trying to open the files in the wrong location, though. ---

To be honest, I am not even sure anymore why I was using that path. I suspect I tried to find the experiments at the time and must have seen them there. Also, when I use the cj50 path I get an operational error: OperationalError: (sqlite3.OperationalError) unable to open database file (Background on this error at: [Error Messages — SQLAlchemy 1.4 Documentation](https://sqlalche.me/e/14/e3q8)) ---

is the default database at `g/data/ik11/databases/cosima_master.db`? I always start a session without any path, e.g., ```auto master_session = cosima_cookbook.database.create_session() ``` and let the cookbook pick the default. (Btw, @ribeirosantosn if you enclose code in triple backticks, e.g., ````` `code` ````` it comes out formatted much better.)
