Dear all,

I failed running the TXT2IOAPI in MEGAN v3.1. Some garbled characters showed up while it reading the CT3.tceq\_12km.csv file like:

#####################################################  
ERROR: Overflow prevented while parsing line PARSLINE  
First 200 characters of line contents are:  
84420,452,165,0,垱@࿮\>HP󂴨ԁmĖ@M?429,461,165,0,0,0,0,0,0  
##########################################################

But I found nothing special while opening the csv file using EXCEL or Notepad++ or any editor else.

I need your help, sincerely!

(PS: If anyone wondering why there isn’t a cantype.f90 file in the preprocessor code, note that the prepmegan4cmaq.cantype.f90 file isn’t in the preprocessor code published on the MEGAN official site, I sent an email to the software author and he gave me one.)

Dear Ionne I’m encountering the same problem relative to prepmegan4cmaq\_cantype not present in the download codes. I sent a message to the contact found on the website (shengting.cui@wsu.edu) but I haven’t received any answer. Could you please share the script or give me another mail address?

Thanks in advance

Dear mazzeoa, sorry for my replying so late, here is the cantype file received from Prof. Alex (the author). Don’t forget to modify the suffix from .txt to .f90

Dear ionnie  
Do you have input files for MEGAN3.1 preprocessor? I don’t have access to these file but I really need them. Thank you.
