Hi,

I have setup the ORCA2\_ICE\_PISCES workload for v4.2.0, but get an error during the run.

```nohighlight
 ===>>> : E R R O R
 iom_varid, file: ./data_DIC_nomask.nc, var: PiDIC not found
  ===>>> : E R R O R
                     iom_open ~~~
 File ./weights_3D_r360x180_bilin.nc* not found

```

Where can I find the weights file, is this something I need to generate in the _WEIGHTS_ directory. I also couldn’t find the `PiDIC` variable in the _data\_DIC\*.nc_ file. Please advise.

Regards

Nitya

Sorry but we provide input files only for the references configuration listed here: [Run the Reference configurations — NEMO release-4.2.0 documentation](https://sites.nemo-ocean.io/user-guide/cfgs.html#list-of-configurations)

Are you using one of these configurations?

Hi, thanks for the note. Yes I am running the ORCA2\_ICE\_PISCES workload which is listed as one of the reference configurations.

OK, just set:

1. in _namelist\_top\_cfg_

```fortran
ln_trcdta = .false. ! Initialisation from data input file (T) or not (F)
ln_trcbc = .false. ! Surface, Lateral or Open Boundaries conditions

```

1. in _namelist\_pisces\_cfg_ set

```fortran
ln_ironsed = .false. ! boolean for Fe input from sediments
ln_ironice = .false. ! boolean for Fe input from sea ice
ln_hydrofe = .false. ! boolean for from hydrothermal vents

```

1. in _namelist\_pisces\_ref_ set (or cleaner copy it to _namelist\_pisces\_cfg_)

```fortran
ln_varpar = .false. ! boolean for PAR variable

```

I think this should be enough
