Hi there, I am trying use the codes from era5grib for WRF. However, upon a few different attempts, codes didn’t run. I keep getting this error: ```auto INFO:py.warnings:/g/data/hh5/public/apps/miniconda3/envs/analysis3-24.04/lib/python3.10/site-packages/xarray/core/dataset.py:274: UserWarning: The specified chunks separate the stored chunks along dimension "time" starting at index 12.

Hi @ChristalX, welcome to the ACCESS-Hive Forum! The traceback you posted is incomplete, it lacks the actual raised exception (error). Would you be able to provide the full traceback including the exception print? From the traceback you shared, it seems to be an error related to internal index selection happening within `xarray` (called by `era5grib`), but I cannot understand the actual issue without the full traceback. Cheers Davide ---

The issue seems to be related to `xarray` not finding all the “time” indexes specified through `conf.get_time_range()` > [@ChristalX](#): > > ```auto > File "/g/data/hh5/public/apps/miniconda3/envs/analysis3-24.04/lib/python3.10/site-packages/era5grib/data_handling/data_combine.py", line 72, in merge_fields_in_time > fields_to_merge[key].add_dataarray(da.sel(time=conf.get_time_range()),realm) > > ``` I am not familiar with `era5grib`, but if you share the command that you ran (that resulted in this error), I can try to reproduce the error and understand what is going on.

Sure thing, Here is the line I ran: ```auto era5grib wrf --namelist namelist.wps --geo geo_em.d01.nc --output GRIBFILE.AAA ``` I got my information from this page: [GitHub - ACCESS-Community-Hub/era5grib: Convert NCI ERA5 archive data to GRIB format](https://github.com/ACCESS-Community-Hub/era5grib) (Legacy run option) I also tried another way from this page - Common use cases: ```auto era5grib -f wrf_era5 --namelist namelist.wps --geo geo_em.d01.nc --output GRIBFILE.AAA ``` But here, I got this error: Model configuration: wrf\_era5 does not exist ---
