Hi @sher ,
as the error message says, file INIT_CONC_1 (/fs2/home/qiaozhi/software/cmaq/CMAQV5.3.3/data/icon/CCTM_ICON_v533_2020case_profile_20200105) is not available when the program is executed. If you do ls /fs2/home/qiaozhi/software/cmaq/CMAQV5.3.3/data/icon/CCTM_ICON_v533_2020case_profile_20200105, do you see the file?
Looking back at your other post on preparing the ICON file, it seems you have a slight mismatch in filenames between what you generated with ICON and what you’re specifying in the CCTM run script. Specifically, in the log file you posted in that other thread, the file was named ‘/fs2/home/qiaozhi/software/cmaq/CMAQV5.3.3/data/icon/ICON_v532_2020case_profile_20200105’ (note the ‘v532’ as part of the filename) while the CCTM log file says the program is looking for ‘/fs2/home/qiaozhi/software/cmaq/CMAQV5.3.3/data/icon/CCTM_ICON_v533_2020case_profile_20200105’ (note the ‘v533’ as part of the filename).
