Hello, I met warning messages in running `smk_nonroad.csh` > ./smkinven.nonroad.capss2018.log: WARNING: No kept pollutants found at line 3385206 . The source will be dropped. > ./smkinven.nonroad.capss2018.log: WARNING: No kept pollutants found at line 3385207 .

The source will be dropped. > ./smkinven.nonroad.capss2018.log: WARNING: No kept pollutants found at line 3385210 . The source will be dropped. I found that the line `3385206` of nonroad inventory file is a `PM10` source: > 3385206 “KOR”,“48121”,“”,“”,“”,“2260005000”,“”,“PM10”,6.252307992e-05,“”,“”,“”,“”,“”,“”,“”,“”,“”,“2018”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“” > 3385207 “KOR”,“48121”,“”,“”,“”,“2260005000”,“”,“PM10”,5.03756127e-06,“”,“”,“”,“”,“”,“”,“”,“”,“”,“2018”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“” > 3385208 “KOR”,“48121”,“”,“”,“”,“2260005000”,“”,“PM10”,9.611049609e-05,“”,“”,“”,“”,“”,“”,“”,“”,“”,“2018”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“” > 3385209 “KOR”,“48121”,“”,“”,“”,“2260005000”,“”,“PM10”,6.276558834e-05,“”,“”,“”,“”,“”,“”,“”,“”,“”,“2018”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“”,“” But I found that `$INVTABLE` (invtable\_hapcap\_cb05soa.txt) has Keep as Y: > PM10 PM10 Y 1.0 N tons/yr Particulate matter, 1 All `PM10` sources are dropped when running `smk_nonroad.csh`. When I ran other scripts (e.g. `smk_point.csh` or `smk_area.csh`, the warnings didn’t occurred. Any comment would be appreciated. Thank you.

I mistook the nonroad inventory path. After fixing, the problem was solved. ---

What is your pollutant here – CPM? Is that pollutant listed in your invtable and other ancillary files? ---

Hi eyth.alison THANKS for your notification ,I had changed the gsref ,gspro,and invtable,but the error still exist.May be there is something wrong with CSV, the last word of the smkinv log tells ‘Error reading raw inventory file PTINV’.I asked several group member,and nobody knows. ![image](https://canada1.discourse-cdn.com/flex027/uploads/cmas/original/2X/9/9ec0413233e7b33ed0cb25ff48108addbe77828f.png) ---

Have you made a small inventory file and posted it for review? ---

Hi eyth.alison Thank you for your help. Maybe there is something wrong with my input csv ,and it got solved after change the format to txt .I found this by download a brand new zip file from website,and find the example inventory formate is txt. ---

Good – glad you figured that out. Yes it’s similar to .csv but not exactly a .csv
