Using NEI Platform 2015 and smoke 4.5(precompiled with platform) I ran merge for all and an error is shown in the output: > ERROR: At least one message’s priority is less than or equal to the exit priority: 1 > ERROR: Level 1 errors or Level 0 warnings found. Check log files, fix inputs, and rerun. Please find the script run screen output (mergeOut.txt) attached. [mergeOut.txt](https://forum.cmascenter.org/uploads/short-url/n4o2tiZGYj8Lqz97lKRRfxfis73.txt) (6.6 KB) The **log** file shows: > \*\*\* ERROR ABORT in subroutine MRGGRID > Could not open file “OUTFILE”. I have attached the run script file (Sector\_merge\_12US2\_2015fd\_cb6\_15j.csh), the sector file (sectorlist\_2015fd\_15feb2018\_v0\_withOnroad.txt) and the log file below(mrggrid\_merge\_log.txt). [Sector\_merge\_12US2\_2015fd\_cb6\_15j.csh](https://forum.cmascenter.org/uploads/short-url/zxTMETd7QV0Etkb4HxETiLSAZD7.csh) (5.4 KB) [sectorlist\_2015fd\_15feb2018\_v0\_withOnroad.txt](https://forum.cmascenter.org/uploads/short-url/jFwik1p7cjqTCAwHV5671DrIMD8.txt) (1.9 KB) [mrggrid\_merge\_log.txt](https://forum.cmascenter.org/uploads/short-url/azTvnQg0KdoHLo6yNZN0uuexX4s.txt) (18.1 KB) The onroad merge program ran successfully. I tried to merge without onroad with the same script as above (Sector\_merge\_12US2\_2015fd\_cb6\_15j.csh) with the modification of one line in the sector file provided below (sectorlist\_2015fd\_15feb2018\_v0\_woutOnroad.txt) and it ran successfully. The log file (mrggrid\_merge\_woutOnroad\_log.txt) and screen output (mergeWoutOnroadOutput.txt) are provided below. [sectorlist\_2015fd\_15feb2018\_v0\_woutOnroad.txt](https://forum.cmascenter.org/uploads/short-url/icdZ9bkS04n7PaxNLwuhrRE3Hv9.txt) (1.9 KB) [mrggrid\_merge\_woutOnroad\_log.txt](https://forum.cmascenter.org/uploads/short-url/2PYECMrtJCm4PZwhQFI9jJguZia.txt) (80.2 KB) [mergeWoutOnroadOutput.txt](https://forum.cmascenter.org/uploads/short-url/yfHYKJiXNS0odQ43nPqDuZaaVuG.txt) (238.3 KB) Does anyone have any tips or advice on how I can go about addressing this issue? Thanks, Kruthika ---

Have you confirmed that you have write permission in the location that it is supposed to be writing the output file and there is not a typo in the path? Can you create a file in the same area manually? ---

Yes, I have confirmed that I have write permission in the location of the output file and I can create a file in the same area manually. ---

We think that Mrggrid may be struggling to overwrite the output file from a previous run. Can you delete the older merged outputs and try again? ---
