Issues with regridding in StartR

Hi @nperez ,

I'm loading data and trying to regrid the ERA5 dataset towards the SEAS5 dataset. Also, trying to convert the longitude to make it go from -180 to 180 by doing longitude_reorder = CircularSort(-180,180) with no success.

The jobs crash and give this error: Error in Apply(list(c(6.26667717718021e-10, 4.67152316829811e-10, 5.24122079070821e-10, : Found one or more margin dimensions with the same name and different length in some of the input objects in 'data'. Calls: do.call -> Apply Execution halted

When running the job, it prints the dimensions of exp and obs, and says that SEAS5 have 91 latitude points but ERA5 have 89 points. Is this a problem to do with the latitude bounds?

Please see attached my code below, and thanks a lot for your help!
