Hello,
I have some emission files. I needed to make change some emissions in one file (file A). And I don’t want to consider other emission files. So, deleted everything inside the those emission files (file size 0 bytes, file B Q1 Q2 and C).
I do not think SMOKE cares whether the file is blank or not. If it is blank, then it will skip to the next file. However, the error message you got with a blank file looks like coming from another internal run script. Not originated from SMOKE.
