Benchmark data ISAM regions not found

Dear all,
when i am running CMAQv 5.3.2 -ISAM with the benchmark data (CMAQv5.3.2_Benchmark_2Day_Input). I change the path settings in run_cctm_Bench_2016_12SE1.csh and EmissCtrl_cb6r3_ae7_aq.nml. but I got a error:

REGION :REGION

 >>--->> WARNING in subroutine OPEN3
 File not available.

 *** ERROR ABORT in subroutine SubhFile_Cell on PE 008
 Could not open REGION

PM3EXIT: date&time specified as 0
Date&time specified as 0
I dont know the reason, Could you please tell me why?

I suggest to first making sure that this file exists and is in the correct format:

/home/Zhangyu/Build_CMAQ/CMAQ_Project/CCTM/scripts/GRIDMASK_STATES_12SE1.nc

Also, in the EmisCtrl*.txt file, you need to point the model to the. This is done by erasing the stuff in one the lines. Change it from:

!<Example> 'ALL' ,'ISAM_REGIONS','ALL',

To:

'ALL' ,'ISAM_REGIONS','ALL',

And undo the stuff you changed with the <Default>
