Hi all, I have a question about an error I see after modifying the PTINV CEMS and nonCEMS inventories to run the EGU sector using as baseline the 2016NEI. If I remove some units from the CEMS FF10 file, I can successfully complete the onetime script, but I see this error with the seasonal one that points to the smkmerge program. > > > WARNING in subroutine CHKFIL3 \<\<\< > > > Inconsistent file attribute NROWS for file INLN > > > Value from file: 8531 > > > Value from caller: 8221 > > > Could not open file set “INLN”. ``` *** ERROR ABORT in subroutine OPENMRGOUT Could not open file set "INLN". ``` I had a look at openmrgout.f but I cannot figure out what file it is comparing against. What I am confused about is the value from file not changing (8531), since the stack groups file is created properly and contains a smaller amount of units (8221). Any suggestions? -Christos ---

After some digging in the specifics of 2016NEI, I found that there is the additional EMISINV\_B1 that I was missing. This is related to 2016 projections of the 2014 EGU fleet and is documented in the 2016NEI TSD.
