one notes that this is a _ **very** old_ I/O API library… Something seems to have happened to the file-name argument for DESC3(). Version at least 3.1 (2010) would log the file-name argument so that you might have a better chance… I don’t know about those “Invalid syntax…” error messages… ---

Thank you for replying! I think there might some issue with reading the mcip files. DENS means air density and RC means precipitation. I think I put the correct path there in the script. Yijia ---

Hi Yijia, Yes, there does appear to be an issue reading the met variables out of the MCIP files. That should be the first issue you try to address. Not sure if it’s related to an issue with I/O API or not as suggested. You’ll need to do a little digger there. I also noticed at the end of the log file you sent an error with the RMySQL package in your R installation. Apparently it is missing based on the error message. You’ll need to install the RMySQL package in order to use the database with AMET. Wyat ---

Dear Wyat; I will look into the mcip inputs. The RMySQL makes me very confused. Actually I am not using database in AMET. I just want to compare the obs with model outputs. I am following the “AMET aqProject Pre- and Post- Analysis Script Guide v1.4” on AMET/doc in GitHub. It did not tell me to how to get away from the database setup. I don’t think I need to set up a database with my purpose of only comparing obs and model. Am I understanding right? The script I am running is “AMET\_v14/scripts\_db/aqExample/aqProject\_pre\_and\_post.csh”. Is it the correct one to run? If not, would you please point me to the right one? Appreciate it a lot! Yijia ---

Since it sounds like you just want the paired model/obs data, you should set the LOAD\_SITEX flag to F, but keep the WRITE\_SITEX and RUN\_SITEX flags set to T. That will avoid AMET attempting to load the site compare output into the database. That should work for you. ---

Since I am not using project or database connection, I want to run the script in the directory of “scripts\_analysis”. For instance, I am trying to get the “run\_scatterplot.csh” to work. However, it keeps giving me error of either “mysql not loaded” or “source config\_file failed”. I suspect I did not know how to configure the running script.Or I missed somewhere. In the “run\_scatterplot.csh”, there is no places to set the locations of obs and model outputs. I have used the combine program to pre-analyze the CMAQ outputs already. So I want to link the observations and combined outputs to the running script. Where should I do this? In the User’s Guide, since it is mainly used to utilize AMET database, the instruction of how to pair and compare obs and model without database is not very clear. Could you give me some hints if possible? Thank you a lot! Yijia ---

Hi Yijia, I assume in the run\_scatterplot.csh script you set the AMET\_DB flag to F, correct? That’s the first thing you need to do. Second, you need to set the environment variable OUTDIR to the location of your site compare output files (the csv files). Note that regardless of whether or not you’re using the database, you still need to specify the environment variables AMETBASE, AMET\_PROJECT and MYSQL\_CONFIG (I realize MYSQL\_CONFIG is confusing since you’re not using the database, but it’s really an AMET config). And if you don’t plan on doing a model-to-model comparison, comment out AMET\_PROJECT2. Please try doing those two steps if you have not already and report back any issues. Thanks. Wyat ---

Thank you very much, Wyat. I did not know I need to input the site compare output. I understand now. Best; Yijia
