[gmx-users] fatal error message

[Derrick Guang Yuh Lee]

Dear Ahmed,

Your error,

Fatal error: number of coordinates in coordinate file (conf.gro, 648)
	     does not match topology (topol.top, 0)

means that you need to adjust your topology file, for some reason or
another, it appears that the molecules in your system were not defined,
i.e. the number of proteins in your system or the number of water
molecules. this is an example of part of the topology file in one of my
simulations:

[ molecules ]
; name  number
DPPC    128
SOL     3655

i think, chances are that the molecule types are not listed, hence
why your topol.top has 0 atoms. I hope this helps.


Sincerely

 - Derrick Lee
