Yes - your SPECIES string is around 280 characters and the file is coded to read a max of 256.
You can open the file sinput.F and search for the line:
CHARACTER( 256 ) :: TXT, TXT2, EMISTYPE
You can change that 256 to 512, for example.
Additionally, find the lines:
READ( JVUNIT, '(A256)', END = 999 ) TXT
Change that A256 to the same number (A512, for example).
After these 2 changes, you will need to recompile the code. Please, report back if this solves your problem.
