Hi Yunqing. It looks like the MEGAN_CTS file is working and you’re using MEGAN 3.2, so that EF file should be compatible. Can you share an ncdump of your file? Here is an example from one that is currently working with CMAQ 5.4:

If you also share an ncdump of your working CTS file it might help reveal any discrepancies in dimensions, etc. A screenshot from ncview might also be helpful to make sure everything looks reasonable.
