CMAQ-CCTM error

When I was running CCTM, CCTM prompted the following error: Is it my setup problem or the emission source problem?

The error message says that the timestep is not available in your stack_groups file.
Can you share a copy of your run script and your CTM_LOG file?

It’s a time-independent file, so the error message saying the timestep is missing is probably a red herring.

The format of the stack_groups file appears incorrect. There is supposed to be one column, and the number of rows corresponds to the number of point sources in the sector. I suggest you compare to the sample point source files that are distributed with CMAQ, and/or consult the SMOKE documentation for creation of those files.

Chris is right. Stack group file is not time dependent and also they are warning message. Error is coming while initializing plume rise. I think @guodp need to check what was the actual error message in a log file.
