Dear all, I have tried to run the MEGAN2.1 model (compiled by _PGI_ ). There is something wrong with the _TXT2IOAPI_ program (_run.txt2ioapi.v32.csh_ ) . When I use the official test data, I got “_ERROR ABORT in subroutine CNVT\_EFS_ I/O error 209 reading input file at line 1”. It looks like there is a problem with I/O, so I tried installing ioapi3.1 and ioapi3.2, but neither solved the problem. I am very confused, please help me. Thank you very much.

This is a text-file error (actually, it would seem, CSI-formatted text), not an I/O API error. The PGI compiler documentation says that 209 is the error-number for “file does not exist”, so you may want to check on that: what does this say: _ls -l /usr/local/MEGANv2.10/Input/MAP/EF210\_USA36.csv_ ---

Dear cjcoats Thank you so much for helping me. When I type _ls -l /usr/local/MEGANv2.10/Input/MAP/EF210\_USA36.csv_， it say _-rw-r–r-- 1 root root 5088966 Jan 19 15:58 /usr/local/MEGANv2.10/ Input/MAP/EF210\_USA36.csv_. It looks like the file exists. I have checked this result several times. I’m not sure if error 209 occurs because I’m running the program under root. I’ve been plagued by this problem for a long time. Looking forward to your reply. Thank you again!
