Greetings everyone!  
My project stucked with following error, that is linked with parameter ‘ref\_wgts’ :  
“Fortran runtime error: Index ‘5’ of dimension 1 of array ‘ref\_wgts’ outside of expected range (4:1)”  
In addition, the model produce only “ocean.ouput” file for ‘mpirun -np 24 ./nemo’ run  
Short description of my project:

- SAS\_ICE configuration built on “ORCA2\_SAS\_ICE” base
- atmospheric forcing input - era5 (using all necessary inputs in namelist\_cfg for Era config)
- weights for salinity and temperature, atmospheric forcings were built successfully with “/tools/WEIGHTS” instrument  
Planning: short-time run for 1-2 days for ice output.  
The main question - what cause this problem?  
Any suggestions will be usefull, thanks for your consideration in advance.
