 Dear Gromacs users,

Thanks for the messages.

Tsjerk,

I was not aware that capital letters denote unpolite. I just used them to highlight the problem so others can easily pick out. Thanks for the suggestions as well.

I modified the file:
*******************************************************************

cpp            = /lib/cpp
define         = -DPOSRES -DFLEX_SPC
constraints    =  none
morse          =  no
integrator     = steep
nsteps         = 2000
; Energy minimizing
emtol          = 100
emstep         = 0.00001
nstcomm        = 1
nstlist        = 10
ns_type        = grid
pbc            = xyz
rlist          = 0.8
coulombtype    = pme
rcoulomb       = 0.8
vdw-type       = cut-off
rvdw           = 0.8
nstenergy      = 10
Tcoupl         = no
Pcoupl         = no
gen_vel        = no
*************************************************


But the message is the same.


As Dallas and others mentioned, I attach the last part of myt .gro file
