[gmx-users] Fatal error in g_enemat using GMX4.5.1

[zhongjin]

Hi all,
   I am using gmx4.5.1 g_enemat ,came across a error,
g_enemat -f pull.edr -groups -emat,
Opened pull.edr as single precision energy file
Will read groupnames from inputfile
Read 1 groups
group 0WARNING! could not find group (null):K-K (0,0)in energy file

Will select half-matrix of energies with 2 elements
Last energy frame read 136 time  135.400          
Will build energy half-matrix of 1 groups, 2 elements, over 137 frames
Matrix of Coul-SR energy ranges from 10000000000.000000 to 0.000000

Back Off! I just backed up Coul-SRemat.xpm to ./#Coul-SRemat.xpm.1#

I have set energygrps  = K  SOL CNT CL  in .mdp file.

I USE g_enemat -f pull.edr -groups -emat,and show:
