[gmx-users] Trouble with the command "g_x2top"

[.翁偉翔]

Dear all,

I had trouble with the command "g_x2top" while trying to generate the
topology file for the molecule SAM. Error came up as followed.

Program g_x2top, VERSION 4.5.5
Source code file: g_x2top.c, line: 505

Fatal error:
No or incorrect atomname2type.n2t file found (looking for amber94.ff)

Does anyone know what could have caused this problem?

Thanks in advance

Felix Weng
