Dear teachers, I used MEGAN32\_prep\_code to generate the CT3.csv, but when I tried to run it in the run.txt2ioapi.v32.csh script, it failed. From the CT3.csv, I found that there were many “100” values present. I think this is the reason why my run.txt2ioapi.v32.csh script failed to run. Why did this happen and how can I solve it?
