National Emissions Inventory Processing

I am (for the first time) trying to process the NEI2014 (for CMAQ on 12US2 grid) using the inbuilt smokev4.5 that comes with the modeling platform, but this is proving a little difficult with some errors. I basically tried to run the nonpoint oil and gas emissions processing script (./Annual_np_oilgas_12US2_2014fd_cb6_14j.csh located at $INSTALL_DIR/2014fd_cb6_14j/scripts/nonpoint/) first and got the following at the end:

Basically, the errors on the screen can be listed in order of appearance as:

  1. ERROR detected in logfile
  2. ERROR: detected in Grdmat​
  3. ERROR: Running smk_run for one-time steps​
  4. ERROR: At least one message’s priority is less than or equal to the exit priority: 1​
  5. ERROR: Level 1 errors or Level 0 warnings found. Check log files, fix inputs, and rerun.​

When I attended to the first ERROR (error in logfile), I checked the logfile and saw that there was an error there:
ERROR: input file not found: SRGPRO_PATH
/$INSTALL_DIR/ge_dat/gridding/CONUS12_2014_v1.3_29nov2016/./USA_100_NOFILL.txt

How can I get the SRGPRO file (USA_100_NOFILL.txt) from the NEI2014 modelling platform?
