hi all, I compiled MEGAN3.2 with gcc, and then started to make the input file of CMAQ online biological source, but an error occurred when running run.txt2ioapi.v32.csh at the end. Does anyone know what the reason is? There is an input file in the network disk ` ``` https://www.gnu.org/licenses/old-licenses/lgpl-2.1.html for conditions of use. ioapi-3.2: $Id: init3.F90 320 2016-02-26 15:55:00Z coats $ Version with PARMS3.EXT/PARAMETER::MXVARS3= 2048 netCDF version 4.1.3 of Aug 8 2023 08:55:59 $ Missing environment variable EXECUTION_ID Value for GDNAM3D: '202004_zhu' Value for GDNAM3D: '202004_zhu' Value for RUN_EFS: T returning TRUE File "GRIDDESC" opened for input on unit: 99 /home/likeco/data9/zhu/MEGAN/MEGANv3.21_Oct_2022/MEGANv3.2_Dec_2021/Input/MAP/GRIDDESC Value for PROMPTFLAG: N returning FALSE File "EFSTXTF" opened for input on unit: 99 /home/likeco/data9/zhu/MEGAN/MEGANv3.21_Oct_2022/MEGANv3.2_Dec_2021/Input/MAP/OutputGridEF.202004_zhu.csv ERROR: Overflow prevented while parsing line PARSLINE First 200 characters of line contents are: gridID,EF1,EF2,EF3,EF4,EF5,EF6,EF7,EF8,EF9,EF10,EF11,EF12,EF13,EF14,EF15,EF16,EF17,EF18,EF19,LDF3,LDF4,LDF5,LDF6 *** ERROR ABORT in subroutine PARSLINE Formatting problem. ``` `attachedhttps://drive.google.com/file/d/1kNCJasLKRomA6irgDApchpRwLcZ26S-q/view?usp=drive\_link, [https://drive.google.com/file/d/1YhrZ45R2oX\_9sFkn1EZ3A219IjA10mHA/view?usp=drive\_link](https://drive.google.com/file/d/1YhrZ45R2oX_9sFkn1EZ3A219IjA10mHA/view?usp=drive_link), [parsline.f - Google Drive](https://drive.google.com/file/d/1HWsfx3g7knJJQfU2Af9Mb74Mce3HKl0z/view?usp=drive_link) ---

Hi Zhu, I’m unable to reproduce your error with GCC and the csv file you provided. Maybe it has something to do with the flags you used when compiling TXT2IOAPI. The flags I used are: ``` FFLAGS = -Wl,--copy-dt-needed-entries -O3 -funroll-loops -finit-character=125 -Wtabs -Wsurprising -ftree-vectorize -ftree-loop-if-convert -finline-limit=512 ``` ---

Hi willison, I just tried the flags you mentioned, but unfortunately I still get the same error. In addition, I would like to ask if the generated CSV file you mentioned is OK.Thank you for your reply ---

Your csv and parsline.f succesfully create a netcdf file for me, so I don’t think the csv is the problem: > ``` > > ./run.txt2ioapi.v32.csh > > This program uses the EPA-AREAL/MCNC-EnvPgms/BAMS/ UNC IE > Models-3 I/O Applications Programming Interface, [I/O API] > which is built on top of the netCDF I/O library (Copyright > 993, 1996 University Corporation for Atmospheric Research > Unidata Program) and the PVM parallel-programming library > (from Oak Ridge National Laboratory). > Copyright (C) 1992-2002 MCNC, > (C) 1992-2018 Carlie J.

I have tried many possibilities, including reinstalling all the libraries required by MEGAN, but the problem still cannot be solved. I will continue to try later. If it is solved, I will reply here. Finally, thank you for your help.
