Hello gmx-users,

i ran grompp and came to such errors like 
-------------------------------------------------------
Program grompp, VERSION 3.3
Source code file: topio.c, line: 405

Fatal error:
Found a second defaults directive, file "/home/wurl/gromacs/share/gromacs/top/ff
oplsaa.itp", line 20
-------------------------------------------------------

i used itp files for my system, and line 18-20 in file "/home/wurl/gromacs/share/gromacs/top/ff
oplsaa.itp" is like :

[ defaults ]
; nbfunc	comb-rule	gen-pairs	fudgeLJ	fudgeQQ
1		3		yes		0.5	0.5

i don't know why this error can happen, i also similar error when using the water model sw.itp
 
Regards!
                    
Sincerely,
