First of all, please check that the reference files for your nudged experiments are available on the platform you would like to run at the location : HSM_DIR/nudging/REFERENCE/CONFIG/fcMEMB/ where REFERENCE is the name of the ocean reanalysis you would like to nudge to ( s4 / glorys2v1 = 2 options available currently ), CONFIG is the ocean model resolution ( ORCA1L75 / ORCA025L75 ) and MEMB is the member.

If you would like to prepare new reference files, their naming should follow the convention : REFERENCE_fcMEMB_YYYYMM_grid_T.nc.gz = one file containing 3-dimensional monthly mean temperature and salinity.
