When running a long simulation it sometimes happens that a single year is missing from in your store directory. On curie that would be, for example,

/ccc/store/cont003/dsm/p529luy/IGCM_OUT/OL2/PROD/secsto/JOB_NAME/SBG/Output/MO

Sometimes LibIGCM has difficulties to copy the history files from the scratch to the store. So it is good to first look in the complementary scratch directory.

/ccc/scratch/cont003/dsm/p529luy/IGCM_OUT/OL2/PROD/secsto/JOB_NAME/SBG/Output/MO

If the missing output file(s) are there, manually copy them to the store. Remember to copy both the SBG and SRF files.
