I have run glycam2gmx.pl script to convert files into gromacs ones. I would like to solavte the sytem using tip5p, but when i run the grompp i get an error

program grompp_d, VERSION 4.5.4
Source code file: toppush.c, line: 1166
Fatal error:

For more information and tips for troubleshooting, please check the GROMACS
