Hi,everyone,I put forward the question yesterday.
When I run the simulation, the system always echo
"Fatal error: number of coordinates in coordinate file (conf.gro, 12032) does not match topology (topol.top, 0)".
Mr Abraham has pointed out maybe there is something wrong with the topol.top file.
Now I put the topol.top here:

Since the conf.gro file is rather large,so I will not paste it here, and the conf.gro seems to be right.What bothers me most is why my computer can't recognizeatom coordinates in the topol.top.Can anyone helpme out?By the way my linux is Fedora Core5,and the Gromacsedition is 3.3.1.
