I am using CMAQv5.4 to run DDM for a simulation but the program fails to generate the ASENS file the log files show the program is done successfully. I am using SAPRC07 and I have only one emission species in sensinput.dat for testing. The ASENS file is created but only has 11k which must be something wrong. Other than that, the simulation seems done successfully, ACONC, CONC and SENGRID are in normal size and the variables in them are reasonable. Looking forward to help.
Best,
K

Thanks for making a new thread.
It is unusual that the program completes and creates a SENGRID files, but not the ASENS files. Does SENGRID have reasonable values?
Another thing to check would be that your GRIDDED\_BEIS actually has NO species values in it. Or run a different sensitivity parameter - maybe one to total NO like this (but with proper formatting):
BIE
EMIS
SPECIES
NO

Yes, I think SENGRID has reasonable values (not infinity or zero). And I had tried different options in seninput.dat, including single species (e.g., NO, SO) and all emissions. All test run come up with the same issue.

I have no idea why you are experiencing this, honestly. The last thing to check would be to see if you are removing the old output files completely and to check that you are writing into a completely clean and empty directory.

I found this and seems it solves the problems:

> Hi @sergey Thank you for this. I tried to limit the amount of species in the run script (changed from ALL to a select few), and I think either the program crashed or it did not limit the reporting to those listed.
Not sure if it is correct, I tried to use medium memory IOAPI and still got the same error. I tried this modification and now the ASENS file seems successfully generated (regular size).

Hi Sergey,
I have got the same error when I run the latest CMAQ 5.4-HDDM(compiled in September 2023). I have limited the output species, used large IOAPI and online MEGAN.
Here’s my sensinput.dat and the error:

And I tried to run CMAQ5.4 HDDM in the former version (compiled in March 2023) and output the normal ASENS file.

This looks like you have an previously created file that exists in your output directory and the code is trying to add to it. I would make sure that you are writing to a completely empty output directory as the first test.

Please, attach the rest of the log file. Or look for text similar to:
```

What follows should be the list of variable.

wry2233,
Please try the 5.4+ branch code. From your log file, it is evident that you are not using the latest release.
When you go to the CMAQ github page ([GitHub - USEPA/CMAQ: Code for U.S. EPA’s Community Multiscale Air Quality Model (CMAQ) which helps in conducting air quality model simulations](https://github.com/USEPA/CMAQ)), the default branch is called “main.” Click where it says “main” and select “5.4+” towards the bottom of the selection list. Using this code will address your issue.

Hi， sergey，I installed CMAQ5.4 and opened DDM in the CCTM module. Strangely, no DDM-related files were generated, only a part of files were generated. What is the matter with this situation

As shown in the comments of the screenshot you posted (“#Additionally requires for CCTM to be compiled for DDM-3D simulations”), DDM-3D needs to be enabled when you compile CCTM, it is not sufficient to only enable CTM\_DDM3D in the run script.
[Step 7 of the DDM tutorial](https://github.com/USEPA/CMAQ/blob/main/DOCS/Users_Guide/Tutorials/CMAQ_UG_tutorial_DDM3D.md#step-7-modify-the-bldit_cctmcsh) shows which line in the bldit\_cctm.csh script needs to be uncommented to compile CCTM with DDM-3D enabled.

Hello, there is another question I would like to consult. Currently, the error is \>\>-- \>\> WARNING in subroutine OPEN3
File not available.
\*\*\* ERROR ABORT in subroutine SubhFile\_Cell on PE 019
Could not open CMAQ\_MASKS
PM3EXIT: date&time specified as 0

Should the CMAQ\_MASKS file be used to mark source emission areas, and what software should be used to create it

If you do not define any region-specific sensitivity parameters in your sensinput.dat control file, you will not need to define a CMAQ\_MASKS file in your CCTM run script and you then also should not uncomment any lines referring to CMAQ\_MASKS in the `&Desid_RegionDef` section of CMAQ\_Control\_DESID.nml
If you do want to specify sensitivity parameters for specific regions, you will need to set these variables and point them to a corresponding file defining these regions. Region files used in DESID emissions scaling as well as DDM-3D and ISAM are described in [Appendix B](https://github.com/USEPA/CMAQ/blob/main/DOCS/Users_Guide/Appendix/CMAQ_UG_appendixB_emissions_control.md#b342-defining-regions).
You can also search this forum for previous threads discussing approaches to create such files by using a search term of “mask” or “region”, e.g. [here](https://forum.cmascenter.org/t/how-to-make-isam-regions-file/2877) or [here](https://forum.cmascenter.org/t/whats-the-maskdatas-format/2919)

First of all, thank you very much for your professional reply. Now I use the DDM module of CMAQ to invert gridded emissions, and finally I want to obtain the sensitivity analysis of grid to grid. In this case, is it necessary to turn on this setting? Now I have turned off this setting, but the operation still reports errors: The ERROR is \*\*\* ERROR ABORT in subroutine DESID\_INIT\_REGIO on PE 029

If you do not want any region-specific sensitivity parameters, you should not have any “REGION” entry in the sensinput.dat file specified in your run script. The structure of sensinput.dat is described [here](https://github.com/USEPA/CMAQ/blob/main/DOCS/Users_Guide/CMAQ_UG_ch10_HDDM-3D.md#10321-ddm-3d-control-file-format) as well as the bottom of the example sensinput.dat file distributed with the code and notes under item 6 that the REGION section is optional.
I am guessing you are working off of the example sensinput.dat file distributed with the CMAQ benchmark case. That example does define two-region specific parameters, one for region “PA” (the state of Pennsylvania) and one for region “NJ” (the state of New Jersey).
To adapt this example to your case, you will have to remove the lines
> REGION
> PA
> REGION
> NJ
If you do want to define regions, you’ll have to refer to them by the region label names defined in CMAQ\_Control\_DESID.nml, mapped from the variable names in your MASK file.
